# How do you write an equation in point slope form that passes through (5,-8) , (-9,-8)?

Since $y$ is unchanged between these two points, while $x$ changes, the slope $m = 0$. The line is parallel to the $x$ axis.
$y - \left(- 8\right) = 0 \left(x - 5\right)$
...using the point $\left(5 , - 8\right)$
More simply, its equation is simply $y = - 8$, but that's not point-slope form.
