Direct proportion. There is a direct proportion between two values when one is a multiple of the other. For example, \ (1 \:\text {cm} = 10 \:\text {mm}\). To convert...
The direct proportion formula allows us to express the relationship between two variables, using an equivalence relationship. When y is directly proportional to x, the value of y ÷ x is a constant value. This is known as the constant of proportionality and is represented by the variable k.
