Answer: y=kx, where k is the constant of proportionality.

Explanation:

Two proportional quantities x and y are related by a constant multiple, or the constant of proportionality, k. You could represent a proportional relationship using the equation y=kx.

Answer 2

A proportional relationship exists between two values x and y when they can be expressed in the general form y = kx, where k is the constant of proportionality.
