Constant of Proportionality

Front

What is the constant of proportionality?

Back

The constant of proportionality is a constant ratio between two variables that are directly proportional to each other.

Front

Express the constant of proportionality in the form y = kx when k = 2.

Back

y = 2x

Front

If y = 3x, what is the constant of proportionality?

Back

k = 3

Front

What does it mean if the constant of proportionality is 'none'?

Back

It means that the two variables are not proportional to each other.

Front

If the constant of proportionality k = 1/2, what is the relationship between x and y?

Back

y = (1/2)x

Front

How do you find the constant of proportionality from a table of values?

Back

Divide the y-value by the corresponding x-value for any pair of values.

Front

If y = 4x, what is the value of k?

Back

k = 4

Front

What is the constant of proportionality if y = 0.5x?

Back

k = 0.5

Front

If k = 10, what is the equation of proportionality?

Back

y = 10x

Front

Identify the constant of proportionality if y = 5 when x = 1.

Back

k = 5
