Front

What is a proportional relationship?

Back

A proportional relationship is a relationship between two quantities where the ratio of one quantity to the other is 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

How can you identify a proportional relationship from an equation?

Back

If the equation can be expressed in the form y = kx, where k is a non-zero constant, it is proportional.

Front

Is the equation y = 75x proportional or non-proportional?

Back

Proportional.

Front

Is the equation y = 3x + 5 proportional or non-proportional?

Back

Non-proportional.

Front

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

Back

A non-proportional relationship means that the ratio between the two quantities is not constant.

Front

If y = 14x, what is the constant of proportionality?

Back

14.
