Constant of Proportionality Practice

Front

What is the constant of proportionality?

Back

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

Front

True or False: The constant of proportionality is also the unit rate.

Back

True

Front

How do you express the constant of proportionality in an equation?

Back

It is expressed in the form y = kx, where k is the constant of proportionality.

Front

If y = 2x, what is the constant of proportionality?

Back

The constant of proportionality is 2.

Front

What does it mean if a relationship is proportional?

Back

A relationship is proportional if the ratio between the two quantities remains constant.

Front

Determine the constant of proportionality for the equation y = 4x.

Back

The constant of proportionality is 4.

Front

Is the relationship represented by the table proportional if the constant is 3?

Back

Yes, if the constant is 3, the relationship is proportional.

Front

Write an equation that represents a proportional relationship with a constant of 1/2.

Back

y = 1/2 x.

Front

Does the table show a proportional relationship if the ratios are not constant?

Back

No, if the ratios are not constant, it does not show a proportional relationship.

Front

What is the unit rate in a proportional relationship?

Back

The unit rate is the constant of proportionality when one quantity is compared to one unit of another quantity.
