What Is The Constant Of Proportionality In The Equation

You see 1 2 is equal to k here pi is equal to k right over there.

So now the equation is just y mx and the constant of proportionality is m. In general you might sometimes see it written like this. A constant of proportionality does not include units. Constant of proportionality is the constant value of the ratio between two proportional quantities.

A direct variation equation has the form y kx where k is the constant of proportionality. How can we find the constant of proportionality. The equation y 5 5x represents a proportional relationship. So c x y so x c y and y x c.

If yes determine the constant of proportionality. For example let s take to variables x and y to be directly dependent in the form above. So the constant of proportionality is 12. It is the ratio of the amounts y and x.
