Is the Constant of Proportionality?

Constant of proportionality is the constant value of the ratio between two proportional quantities. Two varying quantities are said to be in a relation of proportionality when, either their ratio or their product yields a constant.

How do you calculate the constant of proportionality?

The constant of proportionality k is given by k=y/x where y and x are two quantities that are directly proportional to each other. Once you know the constant of proportionality you can find an equation representing the directly proportional relationship between x and y, namely y=kx, with your specific k.

What does it mean when it says constant of proportionality?

: the constant ratio of one variable quantity to another to which it is proportional.
