# How do you write an equation of a line that passes through (-1, -2) with a slope of 0?

Final answer: $y = - 2$

#### Explanation:

We will need to the point slope form. As it what is given, bests suit the formula

$y - {y}_{1} = m \left(x - {x}_{1}\right)$

$m$ is the slope
$\left({x}_{1} , {y}_{1}\right)$ is just the point given

With the information given, fill in the formula

$\left\{\begin{matrix}m = 0 \\ {x}_{1} = - 1 \\ {y}_{1} = - 2\end{matrix}\right.$

$y + 2 = 0 \left(x + 1\right) \leftarrow$ note that two minuses make a plus

$y + 2 = 0$

$y = - 2 \leftarrow$ slope-intercept form

If you want the graph this answer, it would be a horizontal line on the $y$ axis.
