Find the slope of the line shown

Oduvanchick [21]

Answer:

<h2>The slope m = -1</h2>

Step-by-step explanation:

Look at the picture.

The formula of a slope:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

From the graph we have the points (-5, 2) and (-3, 0). Substitute:

$m=\dfrac{0-2}{-3-(-5)}=\dfrac{-2}{2}=-1$
