Proportional and linear functions are almost identical in form. The only difference is the addition of the ‌ b ‌ constant to the linear function. Indeed, a proportional relationship is just a linear relationship where ‌ b ‌ = 0, or to put it another way, where the line passes through the origin (0, 0). So a proportional relationship is ...Definition: Constant of Proportionality. In a proportional relationship, the values for one quantity are each multiplied by the same number to get the values for the other quantity. This number is called the constant of proportionality.
