• B. xy=k
• C. y=kx
• D. None of the above

Answer 1

Answer: (A), (C)

The correct options are
A It describes a simple relationship between 2 variables.
C y=kx

Direct variation describes a simple relationship between two variables. We can say that y varies directly with x.

That is, y=kx, for some constant k.

Inverse variation describes another kind of relationship. We can say that y varies inversely with x.
