You can start with the general form of the equation for a circle whose center is at (h, k) and whose radius is r:
Applying this to your problem, we first have to find the length of the radius, r. I assume that the coordinates that you have given for the radius are the coordinates of the end-point of the radius. Since the radius of a circle begins at the center of the circle, we need to find the distance between the center (6, 6) and the end-point (-4, 3) using the distance formula:
This is the radius.
But we want
Now for the circle:
