#### Answer

slope $=\dfrac{2}{5}$

#### Work Step by Step

RECALL:
The slope $m$ of the line that passes through the points $(x_1, y_1)$ and $(x_2, y_2)$ is given by the formula
$m=\dfrac{y_2-y_1}{x_2-x_1}$
Use the formula above to solve for the slope and obtain:
$m=\dfrac{-3-(-1)}{-3-2}=\dfrac{-3+1}{-5}=\dfrac{-2}{-5}=\dfrac{2}{5}$
