Answer:
slope (m) = 5
Explanation:
(slope)
m = y2-y1 / x2 -x1
Take any of the arbitrary points and plug them into your slope formula.
Let's use (-1,-8) and (1,2) since they are not large numbers (it's easier this way).
-1 (x2) , -8 (y2)
1 (x1) , 2 (y1)
m = -8 - (2) / -1- (1)
= -10/-2
m =5
5
Pick two points, so for example (1,2) and (3,12)
the formula for slope is (y2-y1)/(x2-x1)
plug in your coordinates
(12-2)/(3-1)
10/2
