In this lesson, you will learn how to calculate the slope of a line and interpret the slope. The slope of a line describes how steep the line is slanted. A flat horizontal line has a slope of zero. A vertical line has an undefined slope (or infinite slope). Lines slanted at an angle have slopes in between zero and infinity. We use the slope formula to calculate the slope and use this information to write down the equation of a line, which we can then graph. The slope formula has us calculate the rise between two points on the line and divide this by the run, or horizontal distance, between the points. By calculating the rise over run, we find the measure of the slope of a line.

When I was in Algebra, oh 25 years ago I would ask that same question, "why is this important?" I wasn't trying to be difficult but for me back then and even now I like to know the concrete use cases of whatever I'm learning. It helps me have motivation. I'm preparing to go to college as a 43 year old adult and I'm finding your style of teaching "addictive" to say the least. Thank you so much!
Good luck in your studies!
You are the only teacher who make us understand the concept way better than others
The way you explain everything in detail and not just making us digest the formula is the best thing i have seen on RUclips so far
Please continue making more videos on 11th &12th topics
I have never seen a teacher like you . you always explain the lesson the way it is . I appreciate you
As always, you never disappoint. Your teaching prowess is unique. I have personally learned a lot on your platform. Your effort is appreciated sir.
I appreciate that!
God bless you and your family , Amin
The amount of notes that I can write down from your lessons is unbelievable, Thank you for your time, and helping people who struggle greatly with this subject!!!!
I am so thankful that I came across your site. The thorough way you teach is perfect, the way you repeat and emphasize steps is just what I needed to understanding the rise over run. I will definitely be watching and learning from your other videos.
Thanks so much!
I honestly admire how you teach, it's awesome.
Thank you!
You deserve an award sir. Thank you soooooo much
Sir you are a great teacher and deserve many more views for your videos and I really appreciate your hard work to teach such complex knowledge with so much ease and above all the crux of every topics in very lucid way .🙏🙏🙏thanks for giving such great and valuable knowledge lot of love from bottom of my heart 🙏🙏
This is what real knowledge look for
Very well explained, THANK YOU!!! My biology teacher said i was too analytical, but that's the way I learn!!! Details!!!
Very easy to grasp. Thanks a million.
I used to think ill never use this stuff in my career when i was in high school. The funny part was that i use y=mx+b daily for scaling sensors.
Thank you for making these videos!
I had been struggling to really understand fractions w/negatives.
Not any more. Great lesson.
Awesome to hear!
this is what real knowledge looks like.❤❤❤🎉
The best teaching
YOU are amazing teacher keep it up
When the 1st derivative of a function is zero, the slope is constant. When the 1st derivative of a slope is non-zero, the slope is variable.
God bless you and your family , Amen
You are so smart!!!!!
finally i understand the slope formula!!!!! Thank you so much!!!!
Mr Jason you are indeed a real teacher.i would be happy to have you in sierra leone.please help me on y=px^2+q/xy and x is not equal to zero and p and q are constants 1.find dy/dx 2.show that x^2d^2y/dx^2+7xdy/dx+8y=0
This video and examples just helped me understand this process..This was a great video....awesome job.
Very good way of teaching.
He did an amazing job as we get older we don't forget we have to re_boot. All I ask my instructor that I pay 3,000 to explain. Her response we do have tutors. Ummm no you don't because the tutors don't n refuse to do there job. I just learn something from this instructor .walking in the tread n learn the basic. I still need to understand the graph ❤
I love the way you teach, and it is so easy to understand how to solve the problems now.
Very interesting class. I have enjoyed. Thank you. Would you give me an idea about your slope 1,2 video?
you are awesome teacher I wish you long life
Thank you and you too!
You are such a great teacher! the way you explain is unique, clear, and lucid. I really appreciate you, thanks sir.
❤ a great teacher you are.
Thank you so much.
Omg!! This really helped. Thanks for being so thorough. 😊
Thanks for the expert tutelage. Great work.
Great teaching as always.Thank you, sir.
I am a math teacher and I really admire your lecture.
You are an amazing teacher. Very easy on the eyes as well. Thank you.
Awww shucks thank you!
Thank u so much, you make solving math so much fun
best teacher
Your teaching approach is good.
Make me love math my teacher
THANK YOU... SIR...!!!
I passed an assessment test in math because of you! Thank you Sir!
Very happy to hear this! Congrats!
Can someone send the link to the next videos please ? I'm having some trouble finding them.
There is a playlist
@@edmundtrebus4084 Can you please send a link ? I'd be grateful.
Did you know that the other related word to slope is Romanian "Prislop"( high altitude terrain in a shape of a saddle)?
I think that some returning Dacians brought the word from Birdoswald where Cohorts I Aelia Dacorum were stationed to work on Hadrian's wall in ad 123.
Prislop ,pri'( on, above). + English ,slope'
It is of English/ British origin because there are several words related to it.
Slide, sled, slippery etc.
There are over ,60 Romanian English similar words that neighbors don't have and I've searched them in Wiktionary
Most are described as unknown origin' , and are not via French or Germanic languages.
Another example is
Bulgare( chunk,ball) in romanian from pie , b'h'alg' ( pile)/ bulk.
Thank you.
and doesn't monetize. i wanna meet this man
Ouuuu AND milestones is coming up 🤩thank you
My guy from another planet.
I’m just trying to get back home.
Thank you so much for sharing your knowledge 🙏
Thanks
How about the % in to numbers amazing.
Now I am going to like my math teacher
I wish that you could have been my personal teacher
Make vedeo on triangle
Hello when i try to pick two points (3,2) (5,10) i get m = 4 instead of m = 3
m=5-2/7-4=3/3=1
thanks broo
thanks🙏
Great teacher!
Thank you!
m=3-1/1-0=2/1=2
How about the % in to numbers amazing. 16:30
m=6-2/10-2=4/8=1/2
m=9-5/2-4
Good 👍
love it
y2=3
m=3-3/4-1=0/3=0
Very good
m=rise/run
Im not going to lie, I cheated through 90% of algebra 1, and now am taking algebra 2 and am actually trying. I essentially screwed myself, but these videos are clutching up hard core. Thanks man
Good on you for going back to get the good foundation!
m=2/3
Thank you! I sent this to my niece before the negative slope calculation.
Can't we say a negative slope equals a descent rather than "rise down" which sounds oxymoronic?
Yes, you can certainly think of it as a decent. I speak of it in terms of a rise down, because the slope calculation is rise divided by run. So if you consider the rise as being a negative rising going down then you will automatically get a negative slope of a calculation. That’s why I refer to it that way but you can certainly think of it as a decent just as you stated.
@@MathAndScience thanks!
Actually, thanks for not pointing out my misused expression, oxymoronic.😊
x2=1
Hiw can anyone take a coarse on slope year after year.
1:54 ayyyyyyyyoOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO
m=3
m=y2-y1/x2-x1
I am having a hard time locating these lessons in the members section of the "math tutor dvd" website. Anybody know where to find these more recent uploads?
7th grade math, unit 4, lesson 18
m=1
y axis 9 x axis 4 y axis 5 x axis 2
-1=-1/1
y1=1
why is the slope of a line rise by run and not run by rise
P, phi, theta.
m=-2
y axis 3 x axis 0 yaxis 9 x axis 9
y axis 1 x axis 2 y axis 7 x axis 4
Great
m=0
x1=0
please . I need calculus
formula
slope
yl 1
0
y axis 0 x axis 3 y axis 2 x axis 2
Seems a bit confusing to me that you show the coordinates of points 1 and 2 as (run, rise) when the slope is calculated as rise/run.
What exactly is confusing? The coordinates of the points are the pieces of information necessary to calculate the slope which is the rise divided by the run.
The coordinates of the points are always written (x,y). That does not mean x/y. It's done like that so anyone will know the first number is always the x axis & likewise second number is the y axis. That is just the way graphs are.
y axis 3 x axis 1 y axis 3 x axis 4
rise down or going down
yes
Second
m=y2-yi/x2-x1
