$$m = \frac{3}{2}$$

Work Step by Step

To find the slope of the line, we use the following formula: $$m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}$$ We use points we find on the line to plug into this formula. We can use $(1,1)$ and $(-1, -2)$: $$m = \frac{-2 - 1}{-1 - 1}$$ Simplify: $$m = \frac{-3}{-2}$$ Simplify the fraction: $$m = \frac{3}{2}$$
