Constant of Proportionality Practice

Front

What is the constant of proportionality?

Back

The constant of proportionality is the constant factor that relates 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.

Front

What does the equation y = kx represent?

Back

This equation represents a proportional relationship where 'y' is directly proportional to 'x' with 'k' as the constant of proportionality.

Front

How can you express a proportional relationship in a graph?

Back

A proportional relationship in a graph is represented by a straight line that passes through the origin.

Front

What is the constant of proportionality for the graph if the output is 40 when the input is 1?

Back

The constant of proportionality is 40.

Front

If a table shows values of (2, 6), (4, 12), and (6, 18), is it proportional?

Back

Yes, the constant of proportionality is 3.

Front

What is the formula to find the constant of proportionality?

Back

k = y/x, where 'y' is the output and 'x' is the input.
