Answer

$m=-\frac{8}{3}$

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 shown in the graph: $m=\frac{0-8}{1-(-2)}$ We simplify above and below the fraction bar with subtraction: $m=\frac{-8}{3}$ Then, we move the negative sign out front: $m=-\frac{8}{3}$
