Objectives:
center in a coordinate plane.
 * Develop and use the equations of a circle.
 * Adjust the equation for a circlets move the center to move the

Center not a the origin:
Center (0,2) Radius: 2 the equation that you would use would be --> x^2+(y-2)^2= 4

Center a the origin:
Center: (0,0) Radius 2 the equation that you would use would be --> x^2+y^2=4
