Answer: Choice F. Hyperbola opening up and down.
======================================================
Explanation:
The subtraction symbol between the two fractions indicates right off the bat that we're dealing with a hyperbola. The question now is "How does it open? Does it open up/down? Or does it open left/right?"
To answer this new question, we just need to look at which fraction is negative. The fraction with x in it is negative, so that means the y fraction is positive. The y fraction being positive is the indication of the hyperbola opening up/down.
