swap the coefficients.. I have no idea why that works but it does haha! I couldn't understand why i was getting past paper questions wrong. D1 exam tomorrow, thanks for the help!
Hi, i'm doing the AQA paper on friday, i just need some help on the objective line. As you've said that you need to swap the coefficient and times it by a suitable number, but what if you have a minus. for example, on one off the AQA question, it has p=-x+y ~~~~~~one the graph provided, i can't do a minus as it will go off the graph so how will you do this. thankss
Hi, instead of doing all this line crap with the ruler can i just not do simultaneous equations to the 2 intersecting lines, find the X and Y values then put it into the objective fucntion and maximise/minimise depending on the question?
+Slender Man It also allows you to work out maximised integer values if the given question is for a practical use. For example, the number of cartons of milk needed to make cake - you cant have 2.6.

This was so helpful! I had learnt all about it in school with nowhere near as much depth - thank you!
thank you very much for teaching us for free. humanity owes you one mr. mathmathsmathematics. happy belated teachers day
love you so much!!! Finally see this video after searching for sooooooo long
You really saved my day, thanks so much! This is the most accurate tutorial that I could find!!

D1 exam tomorrow, thanks for the help!
D1 exam tmw too, I can't seem to understand some of the things that I get wrong either. Any other revision type material you could share?
big up mr. mathmathsmathematics
Thanks for the help excellent videos that get straight to the point
it helped a ton keep up the good work
yeah worked that one out cheers buddy
thank you very much.. youre way way way better than my add math teacher who cnt even get her eng. right! lmao
How do you draw the profit line if given P= -x+y?
What do you do when you have a negative coefficient?
i dont get how did u get 1 and 3 for x and y?
you do it by making x = to the maximum or minimum number
big up yahya
Thank you!! :D
Thankyou for the video, I can finally make sense of it xD
Thank you so much !!!! Saved me!!
is the point always at the intersection of two restraints?
Thank you SOOO much!
cheers matey
Thank you sir, it really helped me a lot :) :)

thank u so much
Yes.

The crap with the ruler tells you which two intersecting lines to deal with. Sometimes it's quite hard to tell without it.
Just learn the ruler method. I ended up getting an A on my D1 exam.

your voice, ugh! haha thanks I have a quiz tomorrow
