Constant of Proportionality

Front

What is the constant of proportionality?

Back

The constant of proportionality is the constant factor (k) that relates two proportional quantities, expressed in the form y = kx.

Front

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

Back

k = 2

Front

If y = 1/2x, what is the constant of proportionality (k)?

Back

k = 1/2

Front

What does it mean if a relationship is proportional?

Back

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

Front

How can you determine if a table shows a proportional relationship?

Back

A table shows a proportional relationship if the ratios of corresponding values are equal.

Front

If k = 6, what is the equation of the proportional relationship?

Back

y = 6x

Front

What is the value of k if y = 8 when x = 1?

Back

k = 8

Front

If y = kx and k = 4, what is y when x = 3?

Back

y = 12

Front

What is the constant of proportionality in the equation y = 1/4x?

Back

k = 1/4

Front

If a table shows values (2, 4), (4, 8), and (6, 12), is it proportional?

Back

Yes, the constant of proportionality is k = 2.
