Please explain this to me in the simplest ways possible.

radar · Answer

$$(x+6)^{2}+(y+4)^{2}=36$$ Is this what you are trying to convey?

anonymous · Answer

Yes.

That is a graph of a circle whose center is offset from the origin by 6 and 4.  I believe the radius would be 6 the square root of 36.  Let me do some checking.
