The Supply Function

[@zarashnz]

Wow thank u... what i needed for my exam but didnt remember it...

Thanks sir 🙏🏽

at 9:06 P=4, Qs should be 8, P=5, Qs should be 12.

[@rossmcglothlin]

Good catch! I was just making sure you were paying attention;)

[@mr.avlogs__]

I didn't understand how Qs should be 12 when p=5

[@learnwithmanishkakkar21]

Very nice sir

[@prachigupta5800]

what does negative quantity intercept means?...... if the quantity intercept is zero it means that there is no supply but if quantity intercept is negative then it means zero supply or something else?....i didn't get this point.

Shouldn't it be rise over run at 5:30

[@rossmcglothlin]

Hi Jatin - there are different ways of graphing demand and supply. This method (that is used in the IB programme) has the Q (X) axis as the dependent variable. So the formula has Q as a function of P. Thus, the coefficient of P (the c or d variable) is the slope, but it is run over rise. Many systems don't do it this way, so you should check with your teacher/professor.
TL;DR - If Q is on the left, no. If P is on the left, then yes, it's rise over run.

Thank-you sir

Qs=20+4P please solve it...

[@rossmcglothlin]

Well, you can't really solve it ... You can solve for a given price or a given quantity... So for example if the price is one, the quantity supplied would be 24. If the price is two the quantity supplied would be 28
