Hints:
1) Find the center of the circle. This is the midpoint of the line segment that has the endpoints (3, -2) and (9, -8).
2) Find the distance between the two points. This distance is the diameter. Cut the diameter in half to get the radius.
3) The general equation of any circle is where (h,k) is the center and is the radius.
