Answer
See graph and explanations.
Work Step by Step
Step 1. Divide both sides of the equation by 60 to get $\frac{x^2}{12}+\frac{y^2}{20}=1$ which indicates an ellipse for the equation with $a=2\sqrt 5, b=2\sqrt 3$
Step 2. Graph the equation as shown in the figure.
Step 3. We can identify the equation to be an ellipse from the graph.
