There are many ways to transform a figure on a coordinate plane. This problem requires the movement to be four units horizontally to the right. Using the original coordinate pairs, a positive 4 can be added to each x-value to get the new...

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.
