how do i find center and how do i know this is an ellipse, is this the general form of an ellpse.
thanks if you can help

The general form for an ellipse would be a*(x-h)^2 + b*(y-k)^2 = r^2.
The center of the ellipse is the point (h,k).
For the problem you have stated, h=k=0, so the center is at the origin (0,0).

The most general form of an ellipse is (x-h)^2/a^2+(y-k)^2/b^2=1. The center is at (h,k), with a and b being the lengths of the axes of the ellipse. The longer one is called the major axis with the shorter one being the minor axis.

Small correction to previous answers. These are the general formulas for ellipses with axes parallel to coordinat axes.
