Example: Graphing an Ellipse with Center
To graph the equation , first confirm it is in the standard form of an ellipse centered at . Next, determine the orientation of the major axis. Since and is the denominator of the term, the major axis is vertical. To find the endpoints of the major axis (the -intercepts), set , which yields , resulting in the points and . To find the endpoints of the minor axis (the -intercepts), set , which gives , resulting in the points and . Finally, sketch the ellipse by plotting these four intercepts and drawing a smooth curve through them.
