$y = - x - 3$

#### Explanation:

Because we're given a slope and a point, we can use the point-gradient formula:
$y - y 1 = m \left(x - x 1\right)$

For this question, $m$ is $- 1$ and $\left(x 1 , y 1\right)$ is $\left(- 1 , - 2\right)$. We then put this data into the formula to get:
$y + 2 = - 1 \left(x + 1\right)$
$y + 2 = - x - 1$
$y = - x - 3$
