The relationship wherein the ratio of one quantity to the product of the other two quantities is constant. A. Direct variation B. Inverse Variation C. Joint Variation D. Combined Variation
Two quantities have a proportional relationship if they can be expressed in the general form y = kx, where k is the constant of proportionality. In other words, these quantities always maintain the same ratio. ... Both quantities also change at the same rate: if x doubles, then y will double, and so on.
A relationship where one quantity is a constant multiplied by another quantity is called direct variation. Two variables that are directly proportional to one another will have a constant ratio.
