The steps to follow to solve a problem with direct variation: _____ _____ _____ _____ Let’s go step by step: Find an equation of direct variation where y varies directly as x. One pair of values is y = 7 when x = 35. Y = kx Start with the direct variation equation. 7 = k(35) Substitute for x and y. 7/35 = k, or k = .2 Solve for k. y = .2x ...
