# How do you find an equation parallel to x=7 and passing through (4,- 7)?

$x = 4$
$x = 7$ is a vertical line
Any line parallel to $x = 8$ must also be a vertical line.
That is any line parallel to $x = 7$ must be of the form $x$ '"some constant".
If such a line passes through $\left(x , y\right) = \left(4 , 7\right)$
then $x = 4$
