Answer 1

Answer:

xy=4 AND

y=7x^4

Step-by-step explanation:

B. xy = 4 is a hyperbola, which is a two-piece curve with an asymptote.

C. y = 7x^4

is a quartic, also a curve.

You can tell the other equations ARE linear, because they have no exponent on the variables. (If you solve the "xy" equation for y, the x ends up on the bottom of a rational expression--not linear)
