How to reflect a point over the y=x axis

The video tutorial explains the concept of the X = Y axis, a line where X and Y coordinates are equal. It covers how to graph linear equations, understand points on this axis, and reflect points over it by swapping X and Y coordinates. The tutorial includes plotting examples to demonstrate the reflection process and concludes with a summary and homework assignment.

Explain how to determine the Y value when given an X value on the X = Y axis.

What does it mean for two coordinates to be the same on the X = Y axis?
