Question

Which equation is nonlinear?
A) 4x = 12
B) 3y = 12
C) xy = 12
D) 3x - 6y = 12

Answer 1

I think it's c but I'm not sure to me I think the answer is c

Answer 2

Answer:

In order for an equation to be linear, both the x and the y must have a degree of one, and they can only be added or subtracted, not multiplied or divided. Therefore xy = 12 is nonlinear.
