Constant of Proportionality Practice

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 determine if a relationship is proportional?

Back

A relationship is proportional if the ratio of the two quantities is constant across all pairs of values.

Front

What does the equation y = kx represent?

Back

The equation y = kx represents a proportional relationship where 'k' is the constant of proportionality.
