Write an equation in the form y=mx+b for points
(0,100) (5,80) (10,65) (15,45) (20,25)
----------
Using the 1st and last points:
m = diffy/diffx = -75/20 = -15/4
--> y = (-15/4)x + 100
-------------
These points are not collinear. If you want to graph a straight line thru each pair, there will be 24 of them.

And graph. Please.
