9-44.

Try sketching the circle. The circle to the right has a radius of 2. Try placing it on the axis so it matches the circle described in the problem. The line y = 3x has been graphed for you.

Use the coordinates of the center and the radius to write an equation in general form.
(x − 2)2 + (y − 6)2 = 4

See part (a).

(x − 3)2 + (y − 9)2 = 9
