Graphing Circles

In this online high school algebra math video, you will be shown how to graph circles that are written in standard form. You will be shown how to locate the center and how to find the radius. The first two problems the circle will be centered at the origin, and the last problem the circle is not centered at the origin.
0:00 - problems 1 and 2 (circle centered at the origin)
6:03 - problem 3 (circle not centered at the origin)
