Front

What is the definition of constant of proportionality?

Back

The constant of proportionality is the constant value (k) that relates two proportional quantities.

Front

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

Back

Divide the dependent variable by the independent variable for any pair of values.

Front

If y = kx and k = 5, what is y when x = 2?

Back

y = 10.

Front

What is the relationship between x and y in a proportional relationship?

Back

As x increases, y increases at a constant rate determined by k.
