    This is the standard equation of a cricle! (x-x1)2 + (y-y1)2 = r2 So (x1,y1) = (10,-6) r = 6 Put in the values in the equation! Use the values and expand to get the circle equation! Getting me? :)

    6^2 = 36 Yes it is RIGHT! Now expand by usign the basic algebraic identites! And you'd get the equation of that circle? Got it? :)
