What is the slope of the line between  (7, -8)  and  (5,2 ) ?

Jan 5, 2016

The slope $m = - 5$

Explanation:

The points are
(7,-8)= color(blue)(x_1,y_1

(5,2)= color(blue)(x_2,y_2

The slope is found using formula

$m = \frac{{y}_{2} - {y}_{1}}{{x}_{2} - {x}_{1}}$

$m = \frac{2 - \left(- 8\right)}{5 - 7}$

$m = \frac{10}{- 2}$

$m = - 5$
