Front

What is the Constant of Proportionality?

Back

The Constant of Proportionality is the constant ratio between two proportional quantities, often represented as k in the equation y = kx.

Front

How do you find the Constant of Proportionality from a table?

Back

To find the Constant of Proportionality, divide the value of y by the value of x for any pair of corresponding values in the table.

Front

What is the equation of a proportional relationship?

Back

The equation of a proportional relationship is in the form y = kx, where k is the Constant of Proportionality.

Back

The Constant of Proportionality is 5.

Front

Is the relationship between x and y proportional if y = 1/3x?

Back

Yes, the relationship is proportional with a Constant of Proportionality of 1/3.

Front

What does it mean if a table shows a proportional relationship?

Back

It means that as one quantity increases, the other quantity increases at a constant rate, represented by the Constant of Proportionality.
