If 5 bags of luggage weigh 150 pounds, what is the weight of 1 bag?

Back

30 pounds (150 pounds ÷ 5 bags = 30 pounds per bag).

Front

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

Back

A table represents a proportional relationship if the ratios of corresponding values are constant.

Back

75.

Front

In a graph, if the line passes through the origin, what does it indicate?

Back

It indicates that the relationship is proportional.

Front

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

Back

12 (y = 3 * 4).

Front

What is the formula to find the constant of proportionality?

Back

The formula is k = y/x, where k is the constant of proportionality, y is the dependent variable, and x is the independent variable.

Front

If a table shows the values (2, 6), (4, 12), (6, 18), is this a proportional relationship?

Back

Yes, because the ratios (y/x) are all equal to 3.
