Constant of Proportionality

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

Identify the constant of proportionality in the equation y = 4x.

Back

k = 4

Front

What does it mean if a table of values is proportional?

Back

A table of values is proportional if the ratio of y to x is constant for all pairs of values.

Front

Is the following table proportional? (x: 1, y: 2), (x: 2, y: 4), (x: 3, y: 6)

Back

Yes, the table is proportional because the ratio y/x = 2 is constant.

Front

Determine the constant of proportionality for the table: (1, 5), (2, 10), (3, 15).

Back

y = 5x

Front

Which equation represents a proportional relationship?

Back

y = kx

Front

If k = 1/2, what is the equation of the proportional relationship?

Back

y = (1/2)x

Front

What is the unit rate when the constant of proportionality is k = 3?

Back

The unit rate is 3.

Front

If y = 10 when x = 2, what is the constant of proportionality?

Back

k = 5 (since 10/2 = 5).
