Question 583783
How do I write the standard equation for the circle that passes through the points: 
(-1, 2) 
(4, 2) 
(- 3, 4)
-----------
Pick 2 of the 3 lines between the 3 points and find the perpendicular bisectors of them.
--------
The intersection of the perpendicular bisectors is the center of the circle, (h,k).
The radius is the distance from the center to any of the 3 points, = r.
--> {{{(x-h)^2 + (y-k)^2 = r^2}}}
--------------
Or use determinants.
