Proportionality, constant of proportionality

Front

What is proportionality?

Back

Proportionality is a relationship between two quantities where their ratio remains constant.

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.

Front

What is the equation of a proportional relationship?

Back

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

Front

Is the table of values proportional if (1,2), (2,4), (3,6) are included?

Back

Yes, it is proportional because the ratio of y to x is constant (2).

Front

What does it mean if a relationship is non-proportional?

Back

A non-proportional relationship does not have a constant ratio between the quantities.
