# How do you write an equation in point slope form that passes through P(-2,4) and perpendicular to x=5?

Since the equation $x = 5$ is a vertical line, any line perpendicular to it must be a vertical line
(i..e. the perpendicular line must have the form $y = c$ for some constant $c$).
If the perpendicular line passes through $\left(x , y\right) = \left(- 2 , 4\right)$
$\textcolor{w h i t e}{\text{XXXXX}}$$y = 4$
