Answer:
m = -2
m = DNE
m = -12/9 or -4/3
Step-by-step explanation:
Using the slope equation m = [tex]\frac{y2-y1}{x2-x1}[/tex] :
(-2 - 2) / (1 - -1) = -4/2 = -2
-8 - 8 / 5 - 5 = -16 / 0 = Error / DNE
(This is a straight line at x=5 and therefore doesn't have a slope)
(-13 - -1) / (10 - 1) = -12/9 = -4/3
