    With no xy-term, these are eyeball problems. Both Positive? Ellipse unless coefficients are the same, then Circle. Just ignore x-terms, y-terms, and constants.

    \(9\ne 4\) Ellipse, not Circle.

    No, parabolas can't have x^2 and y^2. x^2 and y -- parabola x and y^2 -- parabola x^2 and y^2 -- NOT a parabola.

    Then the answer sheet is wrong or you have written the problem incorrectly. These are the ONLY two choices if that is what the answer sheet things.
