Find the equation of this. The center of the circle is at (-3,7) and goes through the origin.
-----------------
The radius r is the distance to the Origin.
r+=+sqrt%283%5E2+%2B+7%5E2%29+=+sqrt%2858%29
------
A circle with its center at (h,k) is %28x-h%29%5E2+%2B+%28y-k%29%5E2+=+r%5E2
----
Sub for h & k
