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