If it has an term OR a term but NOT both, then it is a parabola.

If it has both and terms AND...

... the coefficients on the and terms are equal, you have a circle.

... the coefficients on the and terms are not equal, but the signs are the same (i.e. both plus or both minus) you have an ellipse.

... the coefficients on the and terms are not equal, and the signs are different, you have a hyperbola.

The example given is a parabola.
