The foci of the ellipse : .

Length of the major axis is .

Since the  - coordinate of foci are same, the ellipse is horizontal.

The standard form of the ellipse is .

Where center as an origin, ,

Foci , .

Vertices .

  is the length of the major axis and

 is the length of the minor axis.

The foci of the ellipse :  = .

.

Length of the major axis : .

.

Now .

Substitute the values of  and  in .

The equation of ellipse is 

Graph the ellipse.

Graph the equation 

Plot the center point .

Plot the focus points .

Plot the vertex points .

Plot the two points above and below the center  and .

The equation of ellipse is 

The graph of the ellipse :
