#### Answer

$$\text{slope}=-2$$

#### Work Step by Step

RECALL: The slope $m$ of the line that contains the points $(x_1, y_1)$ and $(x_2, y_2)$ can be found using the formula: $$m=\dfrac{y_2-y_1}{x_2-x_1}$$ Use the formula above to obtain: $$m=\dfrac{-4-(-2)}{3-2}=\dfrac{-4+2}{1}=\dfrac{-2}{1}=-2$$
