Question 1119190: An ellipse has a vertex at (0, -5), a co-vertex at (–3, 0), and a center at the origin. Which is the equation of the ellipse in standard form?

Center at the origin and one vertex (0,-5) means the other vertex is (0,5).
Center at the origin and one co-vertex at (-3,0) means the other co-vertex is at (3,0).
So the major axis is in the y direction, and the length of the semi-major axis is 5; the minor axis is in the x direction, and the length of the semi-minor axis is 3.
The standard form for an ellipse with center (0,0), semi-major axis 5 in the y direction, and semi-minor axis 3 in the x direction, is
