In this set of eight problems, we have to match each equation with the correct description of its graph. However, these are test corrections I'm doing and I do not have the previous multiple choice answers so I can deduct from it, but can someone help me?

The equation is xy = 8.

The descriptions that I KNOW are possible are:

A. Parabola with axis x = 0

B. Circle with center (2,-1)

C. Hyperbola with axes as asymptotes

F. Line with slope 3/2

G. Parabola with vertex (2,-1)

H. Circle with center (0,0), radius 4

Okay, I'm pretty sure B and H can be ruled out because the equation doesn't look like that of an equation for a circle. However, I'm not so sure for the others. Any help is GREATLY appreciated!!!!!!!!!!!!!! :D

make a table of values to find a suitable number of ordered pairs to plot, and you will see that C is the correct answer.
