Question

Find the equation of the ellipse with the following properties.

The ellipse with x-intercepts (5, 0) and (-5, 0); y-intercepts (0, 3) and (0, -3).

Answer 1

Intercepts are not just intercepts, they are also points on the ellipse. With all this symmetry going on, you are also being told the vertices and covertices. You should not have missed that.

You may have gotten help MUCH sooner if you had put any work at all of your own in the first post.
