Provide the proper response.Explain in your own words how you can tell from the equation whether the graph is an ellipse or a hyperbola.
What will be an ideal response?
In the equation of an ellipse, the x2- and y2-terms both have positive coefficients. In the equation of a hyperbola, one squared term has a negative coefficient (either x2 or y2 but not both).
