Constant of Proportionality

Front

What is the constant of proportionality?

Back

The constant of proportionality is the constant value (k) that relates two proportional quantities, defined as k = y/x.

Front

Identify the constant of proportionality if y = 1.50x.

Back

k = 1.50

Front

Is the relationship between x and y proportional if y = 3x?

Back

Yes, the constant of proportionality is k = 3.

Front

What is the constant of proportionality if y = 5x?

Back

k = 5

Front

How do you determine if a table represents a proportional relationship?

Back

A table represents a proportional relationship if the ratio of y to x is constant for all pairs.

Front

What equation can be used to find the constant of proportionality?

Back

k = y/x

Front

If x = 9 and y = 15, what is the constant of proportionality?

Back

k = 15/9 = 5/3.

Front

What does it mean if k = 1/3 in a proportional relationship?

Back

It means for every 1 unit increase in x, y increases by 1/3 units.
