Learn how to reflect over the y=x line ex 3

The video tutorial explains how to reflect a figure over the y=x line. It begins by plotting the pre-image points and understanding the properties of the y=x line. The tutorial then demonstrates the reflection process by swapping the x and y coordinates of the points. Finally, it plots the new image points and shows that the reflected figure is symmetrical to the original across the y=x line.

What are the coordinates of the reflected points A', B', and C' if A is (1, 2), B is (4, -2), and C is (0, 4)?

Explain why the y = x line can be confusing for students.
