Answer
$m=-\frac{2}{3}$
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: $m=\frac{0-(-6)}{0-9}$
We simplify above and below the fraction bar with subtraction: $m=\frac{6}{-9}$
Then, we simplify the fraction: $m=-\frac{2}{3}$
