Understanding Reflections in the Y-Axis

The video tutorial explains how to solve a math problem involving the reflection of a line segment over the Y axis. It begins by introducing the problem and asking viewers to attempt solving it. The tutorial then demonstrates the reflection process, focusing on how the X coordinate changes while the Y coordinate remains the same. By analyzing the coordinates of points U and V, the video illustrates the reflection rule and concludes by identifying the correct answer choice.

What is the significance of the Y coordinate remaining unchanged during the reflection over the Y axis?

How can you determine the image of any point on line segment UV after reflection over the Y axis?
