# How do you find the slope of the line through the points (8, -1) and (-7, 4)?

The slope
$m = - \frac{5}{15}$

#### Explanation:

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

(-7,4) = color(blue)(x_2,y_2

The slope

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

$m = \frac{4 - \left(- 1\right)}{- 7 - 8}$

$m = \frac{4 + 1}{- 15}$

$m = \frac{5}{- 15}$
