# How do you write an equation of a line going through (-6,2) perpendicular to y=-2?

$x = - 6$
The equation $y = - 2$ is a horizontal line. For any and every value of $x$, $y$ has the same value - $- 2$.
Therefore a line perpendicular to this is a vertical line. For any and every value of $y$, $x$ has the same value - $- 6$ in this case.
Therefore the equation for this line is: $x = - 6$
