Direct variation. A direct variation, also called direct proportion is a relationship between two variables x and y that can be written as y = kx, k ≠ 0. This situation occurs when the ratio of two variables is constant. When y = kx, we say that y varies directly with x. When z = kt, we say that z varies directly with t.
