Answer
slope $=-\dfrac{12}{5}$
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:
$m=\dfrac{-8-4}{2-(-3)}=\dfrac{-12}{2+3}=\dfrac{-12}{5}$
