# What is the slope of the line passing through the following points:  (8, -1) , (4, 2)?

The slope:
color(blue)(m = (-3)/(4)

#### Explanation:

(8,-1) = color(blue)(x_1,y_1

(4,2) = color(blue)(x_2,y_2

The slope can be found using formula:

m=color(blue)((y_2-y_1)/(x_2-x_1

$m = \frac{2 - \left(- 1\right)}{4 - 8}$

$m = \frac{2 + 1}{4 - 8}$

$m = \frac{3}{- 4}$

The slope:
color(blue)(m = (-3)/(4)
