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
