For this assignment, you will be given information about circles and asked to graph them. In some cases, the equation will be given and in others, information about the center, radius and/or diameter will be given and you will need to write the equation and graph the circle. In all graphs, the center and at least four points on the circle should be labeled with coordinate points – for instance, (4, 0).
