Think about the line y=-1. What does it look like?

It's all the points where y is -1: (0, -1), (2, -1), (-2000, -1)... so it's a line straight up and down. Any line perpendicular to is must be straight across, so it must be of the form

x = something, where all the values of x are the same.

You know that the perpendicular passes through (2,3). What is the x value of that point?

So which of your choices has the same x-value?
