The standard form of ellipse centered at origin with vertical major axis (where ) is .

Observe the given graph :

The major axis is vertical.

The endpoint of the major axis lie 6 units up and down from the center (0, 0).

The vertices of the ellipse are .

So, the denominator of - term is .

Similarly, the endpoint of the minor axis lie 5 units to the left and right of the center at .

So, the denominator of - term is .

Substitute corresponding values in .

The standard form of the ellipse is .

The standard form of the ellipse is .
