Front

What does it mean if two quantities are proportional?

Back

It means that as one quantity changes, the other quantity changes at a constant rate.

Front

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

Back

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

Front

If the constant of proportionality is 5, what is the value of y when x = 10?

Back

50 (since y = 5 * 10).

Front

What is the unit rate?

Back

The unit rate is the ratio of two measurements in which the second measurement is 1.
