The eccentricity of ellipse is $\"\"$ .

The directrix of ellipse is $\"\"$ .

Vertex of the ellipse is $\"\"$ .

The point $\"\"$ is $\"\"$ -axis.

Thus, the ellipse is vertical.

Distance from the focus to the vetrex is the

$\"\"$ is positive and it is to the right of the focus.

Therefore, Standard from this conic with $\"\"$ is $\"\"$ .

Substitute $\"\"$ and $\"\"$ in standard form.
