Write the equation of the line that passes through the given point and is perpendicular to the given line.

Question

1. (-2,5); x = 3

I am heavily confused on how to write an equation with only x. Please explain the steps.

Answer 1

If you graph the equation x = 3, what does it look like? It's a vertical line that crosses the x-axis at (3,0).

What's perpendicular to a vertical line? A horizontal line. I bet you can figure out the rest.
