\

The center of the ellipse is $\"\"$ .

\

The vertex of the ellipse is $\"\"$ .

\

The point on the ellipse is $\"\"$ .

\

The $\"\"$ - coordinate of vertex and center are same, so the ellipse is horizontal.

\

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 $\"\"$ .

\

$\"\"$ .

\

$\"\"$

\

The length of major axis is the distance between center and vertex.

\

$\"\"$

\

The ellipse contains the point $\"\"$ .

\

Let the point is $\"\"$ .

\

Substitute the point $\"\"$ , $\"\"$ and the center $\"\"$ in standard form of ellipse.

\

$\"\"$

\

Substitute the values of $\"\"$ , $\"\"$ and $\"\"$ in standard form of ellipse.

\

$\"\"$

\

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

\

Graph the equation $\"\"$ .

\

Plot the center point $\"\"$ .

\

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

\

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

\

Since the major axis length is equal to the minor axis length, the curve represents a circle.
