You can put this solution on YOUR website! The equation of a circle having the points (2,3) and (-4,5)
-------
Find the center, the midpoint
x: (2-4)/2 = -1
y: (3+5)/2 = 4
The center is (-1,4)
----------
Find the radius, the distance from the center to either point.
r^2 = diffy^2 + diffx^2 = 3^3 + 1 = 10
---------
(x+1)^2 + (y-4)^2 = 10 is the circle
