, where r is the magnitude of the radio, and (a,b) are the coordenates of the center of the circle.In this case, a=2 and b= - 3, because the circle is centered in (x,y)=(2, - 3).The radio, which is the distance between the center of the radio to any point in its border, equals r=2 (because of the scale of the graphic, in this case two squares of the grid equal 2 units, then r=2).Finally, using the previous information to replace in the equation 
was used.
Give the center, radius, and equation of the circle in the graph.
