How to reflect a line segment over the x axis

The video tutorial explains how to reflect points and line segments over the X and Y axes. It begins with an introduction to the concept of reflection, using the X axis as an example. The instructor then explains the process of reflecting over the Y axis, highlighting the change in the sign of the Y coordinate. The tutorial continues with a demonstration of applying transformations to specific points and graphing them to visualize the reflection over the X axis. The video concludes with a reminder to view reflections as mirrored images.

What happens to the Y coordinates of points when they are reflected over the X axis?
