Question 633897
Find the slope of the line that goes through the given points.

(3,-5), (-9,-8)
Find the slope, m
m = diffy/diffx = -3/-12 = 1/4
Use y = mx + b and either point to find b
-5 = (1/4)*3 + b
b = -23/4
--> y = x/4 - 23/4
====================
Do the same for the others.  Don't put a space after the comma in (x,y)
