www.varsitytutors.com › constant-of-variationConstant of Variation The constant of variation in a direct variation is the constant (unchanged) ratio of two variable quantities. The formula for direct variation is y = k x (or y = k x ) where k is the constant of variation . Example 1: If y varies directly as x and y = 15 when x = 24 , find x when y = 25 . Find the constant of variation.
