\

The ellipse is $\"\"$ .

\

Divide each side by $\"\"$ .

\

$\"\"$

\

The ellipse which is in the form of $\"\"$ , $\"\"$ has foci at $\"\"$ where $\"\"$ , and has verticies at $\"\"$ .

\

$\"\"$

\

Consider $\"\"$ .

\

Rewrite this equation in the form of $\"\"$ .

\

Where $\"\"$ and $\"\"$ .

\

$\"\"$

\

Therefore, $\"\"$ .

\

Therefore, foci is at $\"\"$ .

\

Vertices is at $\"\"$ .

\

Graph :

\

(1) Draw the coordinate plane.

\

(2) Graph the ellipse $\"\"$ .
