## why do we use constant of proportionality

In mathematics, two varying quantities are said to be in a relation of proportionality, if they are multiplicatively connected to a constant, that is, when either their ratio or their product yields a constant. The value of this constant is called the coefficient of proportionality or In this case y is said to be directly proportional to x with proportionality.
