\

The ellipse is $\"\"$ .

\

Since $\"\"$ , the ellipse is vertical.

\

Thus, the $\"\"$ -coordinate of vertices and focus are same.

\

The standard form of ellipse is $\"\"$ ,

\

where $\"\"$ is the center of the ellipse, $\"\"$ is the length of the major axis and $\"\"$ is the length of the minor axis.

\

The distance between center and vertex is $\"\"$ .

\

The distance between center and focus is $\"\"$ .

\

$\"\"$ .

\

Consider $\"\"$ .

\

Compare the above equation with $\"\"$ .

\

Graph the ellipse.

\

Graph the equation $\"\"$ .

\

Plot the center point $\"\"$ .

\

Plot the focus points $\"\"$ and $\"\"$ .

\

Plot the vertex points $\"\"$ and $\"\"$ .

\

Plot the two points above and below the center $\"\"$ and $\"\"$ .
