Answer
y = -2
Work Step by Step
The line x = 5 is a vertical line, therefore a line that is perpendicular to it (intersects it at 90 degrees) will be horizontal. So, every value of y on the line will be the same. Since the line goes through the point (3, -2), it must have a y value of -2. As a result, you can conclude that the line is y =-2.
