Find the slope of the straight line

Question

(2,3) (-1,5)

(-5,-2) (-3,-4)

(2,5) (4,8)

Answer 1

slope is change in y coordinates divided by change in x coordinates ("rise over run")

1st two points have slope (5-3)/-1-2) = 2/-3 = -2/3

2nd pair of points have a line through them with slope = (-4--2)/(-3--5) =--2/2= -1

3rd pair have slope (8-5)/4-2) = 3/2
