(-5, -2). Sketch the reflection of line segment AB about the line y = x.

As I understand this concept, I must show that the line y = x is the perpendicular bisector of the line segment AB.

Two points are given. This tells me to find the slope m.

m = (-2 - (-2))/(-5 - (-1))

m = (-2 + 2)/(-5 + 1)

m = 0/-4

m = 0

When m = 0, we are talking about a horizontal line.

Where do I go from here?
