Answer

$m=-\frac{5}{2}$

Work Step by Step

To find the slope, we use the formula $m=\frac{y_2-y_1}{x_2-x_1}$. We plug in the $x$ and $y$ values from the points shown in the graph: $m=\frac{-3-(2)}{0-(-2)}$ We simplify above and below the fraction bar with subtraction: $m=\frac{-5}{2}$ We write the negative sign out front: $m=-\frac{5}{2}$
