I. Direct Variation: y varies directly as x or y is directly proportional to x (y = kx) where k is the constant of proportionality or constant of variation. As x gets larger, y gets larger or as x gets smaller, y gets smaller. A line with a y-intercept of 0 is a direct variation. Data that represents direct variation:
DIRECT AND INVERSE VARIATION WORKSHEET
Direct and Inverse Variation Worksheet Name:_____ Find the Missing Variable: y varies directly with x. If y = -4 when x = 2, find y when x = -6. y varies inversely with x. If y = 40 when x = 16, find x when y = -5. y varies inversely with x. If y = 7 when x = -4, find y when x = 5. y varies directly with x.
