Always True

Work Step by Step

An equation is called a direct variation if it is in the form of $y=kx$, where, $k \ne 0$ is the constant of variation. The value of the constant of variation is obtained by dividing x: $k=\frac{y}{x}$ If q varies directly with p, then the equation of the direct variation is $q=kp$ Thus, the variable p also varies directly with q. So the statement is always true.
