Answer
joint variation
Work Step by Step
Recall:
A joint variation involving two variables is represented by the equation $y=kxz$ or, in the case of a power of $x$ and/or $z$, $y=kx^mz^n $where $k$ is the constant of variation.
The given equation is in the same form as the equation above with $k=6$.
Thus, the given equation represents a joint variation.
