What is the equation of the circle passing through (12,1) and (2,-5) with center on the line 2x-5y+10=0.
Please help me with this and show the solution... Thanks!

Equation of circle centered @ h,k where h is x coordinate and k is y coordinate on x-y graph
Plot ihe two points and the given line on graph paper.Connect the two points and find the midpoint of the resulting line using its slope diagram. Erect a perpendicular at the midpoint by taking the negative inverse of that slope.Draw the line with this new slope from the midpoint crossing the given line.The intersection is the center of the circle.(h,k). From this point draw aline to either given point.Erect a new slope diagram and calculate the radius.Plug values into the above circle equation.
