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]}
