Constant of Proportionality (Tables)

Front

What is the constant of proportionality?

Back

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

Front

What does a constant of proportionality of 45 mph indicate?

Back

It indicates that for every hour, the distance traveled is 45 miles.

Front

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

Back

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

Front

If a table shows values of x and y, how can you tell if they are proportional?

Back

If the ratio y/x is constant for all pairs of values, then they are proportional.
