Variation

Variation

Variation. Unit 13. Direct Variation. The variable y varies directly as x if there is a nonzero constant, k, such that y = kx . The equation y = kx is called a direct variation equation and the number k is called the constant of variation. Steps:. Plug in the given information to find k.
