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

What does it mean for a relationship to be proportional?

Back

A proportional relationship is one where two quantities maintain a constant ratio or rate.

Front

How do you identify a proportional relationship from a table?

Back

A relationship is proportional if the ratios of corresponding values are equal.

Front

What is the constant of proportionality if y = 10x?

Back

The constant of proportionality is 10.

Front

If the constant of proportionality is 3, what is the equation?

Back

The equation is y = 3x.

Front

What is a unit rate?

Back

A unit rate is a comparison of two different quantities when they are combined together, expressed as a quantity per one unit of another quantity.

Front

How can you determine if a scenario is proportional?

Back

Check if the ratio of the two quantities remains constant as the values change.

Front

What is the constant of proportionality for the table: (2,4), (4,8), (6,12)?

Back

The constant of proportionality is 2.

Front

If y = kx and k = 1/2, what is the equation?

Back

The equation is y = (1/2)x.

Front

What does 'non-proportional' mean?

Back

Non-proportional means that the relationship between two quantities does not maintain a constant ratio.
