Mars orbits the Sun in an elliptical path whose minimum distance from the Sun is 140 million miles and whose maximum distance from the Sun is 160 million miles. Supppose the Sun represents one focus of the ellipse.

A. Draw the Sun, Mars, and Mars' orbit on a Cartesian plane where each unit is 10 million miles.

B. Write the standard form of the equation for the elliptical orbit of Mars around the sun, where the center of the ellipse is at the origin.
