Reflecting a triangle over the y axis

The video tutorial explains how to reflect geometric figures over the Y axis. It begins with an introduction to the concept of reflection, followed by a detailed explanation of the rules for reflecting over the Y axis. The instructor then demonstrates how to apply these rules to specific points, transforming them into their reflected counterparts. Finally, the tutorial shows how to plot these reflected points on a graph, providing a visual representation of the reflection process.

Explain how to plot the reflected points after applying the reflection rule.

What is the significance of the Y axis in the context of this reflection?
