#### Answer

$m=-9$

#### Work Step by Step

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: $m=-9$
