You can put this solution on YOUR website! Find the center and the radius of the circle, then graph the circle.
x^2+y^2+6x-4y-203=0
--------
Complete the square on the x and on the y terms::
x^2+6x+9 + y^2-4x+4 = 203+9+4
------
(x+3)^2 + (y-2)^2 = 216
-----
Draw a circle with::
center at (-3,2)
radius = 14.7
