Question

How do you write an equation of a line Perpendicular to x=5 passing through P(-3,-2)?

Answer 1

`y=-2`

Explanation:

`x=5` is a vertical line.
So any line perpendicular to it is horizontal;
that is, it has the form `y=k` for some constant `k`

Since the desired line goes through `(-3,-2)`
the y-coordinate is `(-2)`
and
the equation is `y = (-2)`
