Front

What is the constant of proportionality?

Back

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

Front

The constant of proportionality is also the unit rate. True or False?

Back

True

Name the constant of proportionality if the relationship is y = 40x.

Back

40

Front

What does a constant of proportionality of 5 mean in a proportional relationship?

Back

It means that for every unit increase in x, y increases by 5.

Front

If the constant of proportionality is 3, what is the value of y when x = 4?

Back

y = 12 (since y = 3x, then y = 3*4).

Front

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

Back

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