Hi! The equation for finding the slope given 2 points is

. With the points given, we can plug those into the equation, giving

, which is the same as 2/2, or 1/1. So the numerator, or the top number would just be 1.
The answers are...
a) -3
b) 6
c) 17
If I got it correctly, the question is what is 24x^2y^6-16x^6y^2+4xy^2 divided by 4xy^2 and the answer is 6xy^4-4x^5+1.
D. 6
I hope this helps you out! :D
