How do I graph the equation x^2+y^2+6x-16y+48=0
I've tried to isolate y, but I'm having a lot of trouble with it.
===============
x^2+y^2+6x-16y+48=0
x%5E2%2B6x%2B9+%2B+y%5E2-16y%2B64+=+-48%2B9%2B64+=+25
%28x%2B3%29%5E2+%2B+%28y-8%29%5E2+=+25
y-8+=+sqrt%2825+-+%28x%2B3%29%5E2%29
y+=+8+%2B+sqrt%2825+-+%28x%2B3%29%5E2%29
y+=+8+-+sqrt%2825+-+%28x%2B3%29%5E2%29

You can plot points, or put the center at (-3,8) with r = 5
