# How do you write an equation that contains points (-2, -7) and is parallel to x=4?

$x = - 2$
$x = 4$ is a vertical line; so any line parallel to it must be a parallel line; that is it must be of the form $x = c$ for some constant $c$
If the required line goes through $\left(x , y\right) = \left(- 2 , - 7\right)$ then $x = - 2$ at that point and therefore must be equal to $- 2$ for all points (to be a vertical line).
