How Do You Use a Graph to Reflect a Figure Over the X-Axis?
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.

What is a Reflection?
There are many ways to transform geometric figures. This lesson will illustrate how to reflect figures over a line to get a mirror image of the figure. The teacher will draw three different reflections: one as reflected over the y-axis,...
