X - 62 y 52 152. 6 3 25. To illustrate how the equation of a circle works lets graph the circle whose equation is.
Identify the radius and the center.
If the circle is translated downward units such that the circle is tangent to the -axis the equation becomes. X 2 y 2 Dx Ey F 0 where D E F are constants. Then graph the circle. Now you have the coordinates of the center and the radius and that is all that is necessary to write the standard equation of the circle.
