Homework Help: Algebra

Posted by Soly on Thursday, November 22, 2007 at 7:48pm.

I am not too sure about this problem. Can you please help me?

Graph the ellipse and locate the foci.

9x^2=144-16y^2

I got (- squareroot 7, 0) and (squareroot 7,0), but I was looking at one problem in one book similar to it, and it had the answer as (0, - squareroot 7) and (0, squareroot 7).
