You can put this solution on YOUR website! find the equation of a circle with endpoints (1,1) an (5,5).
-----------------
"Endpoints" must mean on a diameter of the circle, since a circle has no endpoints.
---------------
The center is the midpoint, (3,3).
Its radius is 2sqrt(2)
--> (x-3)^2 + (y-3)^2 = 8
I can provide additional details if needed. email me via the thank you note.
