Answer by Jk22(389)   (Show Source):
You can put this solution on YOUR website! Circle : (8,-5),(10,-7),(6,-7) and a center of (8,-7)
Assuming it is a circle : we can take the distance between any point and the center : |(8,-7)-(6,-7)| = |(2,0)| = Sqrt(2^2+0)= Sqrt(4) = 2
it is easily verifiable that all 2 other points give the same distance.
