Answer:
1.

2.

Explanation:
The equation of the ellipse is

1. If the vertex of the ellipse is at point (6,0), then a=6.
If the co-vertex of the elllipse is at point (0,-5), then b=5.
The equation of the ellipse is


2. If the vertex of the ellipse is at point (4,0), then a=4.
If the co-vertex of the elllipse is at point (0,3), then b=3.
The equation of the ellipse is
