$m=-9$
To find slope, we use the slope formula: $m=\frac{y_2-y_1}{x_2-x_1}$ We plug in the values for $x$ and $y$: $m=\frac{-9-0}{1-(0)}$ We simplify the expression using the order of operations: First, we simplify above and below the fraction bar by subtracting: $m=\frac{-9}{1}$ Then, we divide: $m=-9$
