WebMay 2, 2024 · Solve a proportion. If x and y vary directly, it means y = kx, where k is the constant of proportionality. For any pair (x, y), we have y/x = k. We have (-6, 15) as one set of values, and we have (8, y) as another -- where y is unknown. Solve the proportion: 15/-6 = y/8. Finish the problem by "cross-multiplying", and solving for y. You should get y = -20.
