Linear Demand Equations - part 1(NEW 2016)

This is an update to the 2012 version of the lesson introducing how to determine an equation for demand using price and quantity data from a demand schedule or a demand curve. In parts 2 and 3 of this lesson we'll examine how changes in price and the non-price determinants of demand will lead to movements along a demand curve or a change in the 'a' and 'b' variables and a shift in demand.

This videos is an absolute diamond. I love the way you explained it without any assumptions or skips.

[@alexanderburrows5336]

You just saved me from a stroke! Went through a ton of videos and this is by far the one that is most straight forward and actually EXPLAINS everything without assuming. Thank you!

[@PancakeRecipe_]

7 years ago and yet still so helpful. i was stressing out, God bless you abundantly. you have no idea how much you're helping!

[@nikisnoona3845]

I am a university student from Bangladesh who was struggling with math and and math related syllabus for days. But thanks to you I am learning and clearing my terribly mixed up information on liner equation. No one was able to make me understand this topic as much as you did and I am very thankful for that.

[@kerripayne9123]

Thank you so much for this video - is was the absolute easiest explanation that I have heard for the demand function and it helped me TREMENDOUSLY on both my MBA homework and mid-term exam. THANK YOU!!!!

[@csmayankagrawal]

YOU ARE THE BEST FOREIGN LECTURER WHOSE EXPLANATION AND PRONUNCIATION ARE VERY CLEAR & EASILY UNDERSTANDABLE

[@JLM-ge2xm]

JUST WOW! HANDS DOWN! EVERYTHING WAS EXPLAINED WELL!

[@josequinones2031]

Thanks a lot, you saved me from almost droping from my class, I didn't understand until now!
I appreciate your help!

[@chanelcoppens614]

Thank you Jason, from the bottom of my heart. I have spent hours and hours crying over economics. As a history student, i cannot do math, it is a foreign language to me, but this made understand how to actually calculate the demand function. I might actually pass now. I owe you my life, my sanity, my loyalty. I am forever in your favor. You are a saint, I shall think of you Jason, when the time has come to take my exam and once again thank my only true maths-saviour Jason Welker. Have a wonderful life.

[@jasn3506]

ditto.

[@jackiengai860]

👍 👍👍 🙏 🙏 🙏 😘 very well explained. the best expression ever i saw in terms of details and speaking speed. 👏👏👏👏👏 10:28 also your accent is clear 👍

[@sougata1980]

This is THE Video every student should watch if they want get concept clear for demand supply curve. Thank you so much

[@GetToThePointNYC]

YOU JUST LITERALLY SAVED ME FROM DROPPING MY ECONOMICS CLASS! Thank you soooooo much

[@worldsystems9576]

I can't believe it can be this good

[@Nurj81]

What a great explanation!! Thank YOU for creating this lesson.

[@jeffperra]

Thanks...could not for the life of me figure out how to find the demand curve equation. 3-4 minutes after watching your clip and I'm all set.

[@raime3488]

Thank you so much! I was struggling to understand my professor with this topic. But finally, I get to know how to do the whole thing.

[@shammaalali352]

But isn’t the slope for demand is price over quantity

[@apriljoycalmada8103]

You are a gift from heaven! Thank you!

[@KimSiever]

Thanks so much. You’re a life saver.

[@muskanmishra5581]

Brilliant explanation of why q=a-bp represents linear demand equation 👏👏

[@MsDARAAN]

Thank you so much!

[@sphokazintsalaze]

Amazing work you're doing here Jason. Thanks and God bless

[@akuntansiolahdata5225]

Thank you so much sir, wish you always happy and healthy

[@andrew3905]

absolutely saved. had to learn this all by myself for a report and got stumped because every site i looked to left out the the crucial detail of “b” being the inverse of the slope

[@bageshwardhampariwaar44]

Thanks 🙏🏻 it was easy to understand..keep it up 👍🏻

[@bageshwardhampariwaar44]

Can we use both the formulas to find slope Y=a+bX and Q=a+bP??

[@amirestebari1470]

Thank you very much. I had difficulty understanding this equation but after watching your video, my problem is solved.

[@samsonnelson7301]

Is it possible for us use the same quantity and price we used to find b to find be to find a?

[@leolcjt]

Holy hell!! My brain exploded! This was way easier to understand than my textbook.

[@e02100]

This has REALLY helped so much!!! Thank you!!!!

[@monishamangwani449]

Thank you for explaining this so well!

[@obhenx]

You saved my life, Prof..! thanks a lot..

[@kundakamilo5483]

I will ace my mids all thanx to you 🙏🏾

[@XDbasketball]

isn't it Qd = a-bP??

[@JasonWelker]

the 'b' variable is always negative. 'b' = change in Q/change in P, which will be negative due to the inverse relationship between P and Qd. So the equation turns out to be Qd = a + (-b)P which is the same as Qd = a - bP.

[@rajantiwari5628]

No you dumbo!!

[@Kabaghe]

Exactly 💯😌

[@azellebahadory936]

Thank you for breaking this down! An excellent explanation.

[@puikalee9201]

gosh, this video explains better than my uni professor. Thanks so much!

[@formanauto6034]

Good evening sir. Thanks a lot

[@kadmani]

that handwriting is so neat :o

[@faisalsaood360]

marvelous and so very great ....you know ,,,,for years i ve been finding and thinking about how to determined demand equation and for your astonishment even no book helped me like the way it should be taught in a book .....now after seeing your lecture i got complete idea ..........God bless you ........... you are great .......

[@E22]

Econ is life

[@lisettearena]

Thank you so much! Very helpful!

[@hamodehamode9394]

You helped me a lot
Thanks
You are from the bests

[@amirestebari1470]

...but isn't linear demand equation 'Q = a - bp' ? I think 'Q = a + bp' is for supply!

[@zeryab555]

actually, both equations are same ( Q = a + bP) but the only difference depends upon b ( the slope). If b is negative its demand equation ( Q = a - bP) and if b ( the slope ) is positive it is supply equation ( Q = a + b P). Demand curve has a negative slope and the supply curve has a positive slope.

[@055wijewardanalbsu3]

watch the whole video brother.

[@BanditapatowaryArt]

Thank you🙏

[@classicytuber3104]

Your the best thanks so much

[@johanesogwari3309]

[@truman5560]

this guy is amazing

[@mothernature4576]

Such an easy explanation

[@battulga43]

Thank you! great explanation.

[@jyotibatra8910]

If we have only demand function then how can we draw a demand schedule. And what price difference should be taken in schedule

[@momtahenagamer5855]

Thanks for your explanation

[@victoriachamberlin3461]

thank you! This helped a lot! Also, "depependent" lol

[@lorenzorichards7093]

😂

[@freedman1405]

Hello! If quantity demanded is the dependent variable, why is it that it is on the x-axis instead of the y-axis?

[@anushcheema7100]

same question

[@yashigupta7245]

It is because that the graph of demand curve is based on the inverse demand function where quantity is taken as independent variable

[@mudithamalinda8464]

Thanks A LOT................................................

[@seniorax6380]

Tnx For Expaling This

[@TheVDPJMb]

When I try to find the "a" variabel with Q100 and P2.5, the "a" variabel is 350.. Is that correct?

[@odinlund8253]

Dont think anyone is gonna reply tbh

[@_grxnny]

Thank you! This helped me a lot.

[@Art36o]

You saved my brain

[@heinkenival4078]

Thank you for the song!

[@Elected_Official]

Sir, you are the best !

[@DumbleRoldtheHeadMaster]

why the value of quantity demanded when the price of 1.5 change from 330 to 300?

[@Frootyloops629]

wow so glad i met you

[@tadiwanashechimuka8324]

That song in the beginning is really good

[@bharathiyamanth7338]

Thanks a lott , it helped me very much 🙏🙏

[@viane123456]

If i have a equilibirum condition and demand equaltion can i derice supply function?

[@enelrahcreivaj]

Clear! Thank you! ♥

[@lorenzoramos6216]

may I ask given the example provided by our prof, I tried picking out any Q2 and Q1 from the QD and QS but the b (Q2-Q1/P2-P1) I'm getting is different whenever I tried using the other pairs

[@emalynfrancis5635]

what if there is no number attached to the demand schedule
How to fine the numbers of Q= a + b p

[@rebeccaonyango5799]

Hellow...why did you only choose a price of 2 and quantity of 200
And not any other i.e. price os 1.5 and quantity of 300
Kindly explain

[@danielmworia1240]

Awsome, Just what I needed thanks mate

[@dariusaliyu3103]

having a problem
can u help out

[@MohamedAhmed-he2du]

Thants was great thanks ❤

Bravo 👏🏿

[@leatherdump860]

How to solve Quantity Demanded and a given price??

[@yemcity7867]

Beautiful lesson, Thank U

[@ParminderKaur-in8sw]

can we derive supply equation from demand equation, MR equation and MC?

[@shashankkaurav6375]

Thanks

[@supitchasokrai9883]

Thank you so much 🤍🤍

[@imemeuwu]

Thank you so much 🙆‍♀️🙆‍♀️🙆‍♀️

[@mkyeluri]

when Price and Demand are inversely related to each other, how could this equation Q = a + bP correct? Shouldnt it be Q = a - bP?

[@roseannie9932]

I’m confused myself😐

[@DariaAleshkova]

Thank you so much, kind sir! My textbook explains this horribly!

[@deadenderbg1297]

i agree

[@mohamoudabdishakour1095]

thanks, you really been helpful ❤

[@omarsimpson8414]

This video just opened my mind , thanks alot!!

[@peekaboodoraemon3473]

How to get the price when it’s not given?

[@maeabegailcambaya4016]

Thank youuuuu!

[@wilmarvillanueva1]

For some reason the problem I did had the Q on bottom and P on top

[@ishu-v9i]

Thank you sir

[@formanauto6034]

Good morning sir. Please explain rise and run again in simple way, similarly if price 1$ increase, how much does the qty demand fall using rise and run concept.
Sir when price is decreasing and why do we say, it's rise rather we should say fell and run.
Your comments please.
Thanks and Regards
Raja Aurangzeb from Lahore Pakistan.
