The center is

The lengh of the major axis is

The length of the minor axis is

#### Explanation:

The general equation of the ellipse is

The center is

The foci are

The center is

The lengh of the major axis is

The length of the minor axis is

To determine the foci, we need

Therefore, the foci are F

graph{(y^2/18)+(x^2/9)=1 [-11.25, 11.25, -5.625, 5.625]}
