Constant of Proportionality

Front

What is the constant of proportionality?

Back

The constant of proportionality is the constant value (k) that relates two proportional quantities, expressed as y = kx.

Back

y = 1.50x

Front

What does it mean if a relationship is proportional?

Back

A relationship is proportional if it can be expressed as y = kx, where k is a constant and the ratio of y to x is constant.
