I need some help with a slope formula?

Using the slope formula
m = y2 – y1

x2 – x1

find the slope of the line determined by this pair of points:


(-2, 5) and (1, -5)

(x1, y1) = (- 2, 5)
(x2, y2) = (1, - 5)
Slope of the line joining the two points is
m = (y2 - y1)/(x2 - x1)
= (- 5 - 5)/(1 + 2)
= - 10/3
