Virtual Nerd: How Do You Use a Graph to Reflect a Figure Over the X Axis?

Reflection is a type of transformation. Flipping an image over the y-axis is easy if you follow the steps in this video to perform the reflection. [3:42]

A reflection is just what you think it is, a mirror image. So how do you reflect a figure on a graph? Just flip it over. The teacher illustrates how to select a line of reflection (the x-axis) and make the calculations to flip the figure.
