Tell whether the relationship is a proportional relationship. Explain why orwhy not.

A graph is proportional if a straight line can be drawn through the points and it crosses through the origin. A proportional relationship for objects occurs when the object number increases or decreases and a value of the object increases or decreases at a consistent rate.

1. C

A line can be drawn through the points, however it would not cross through the origin.

2. A

As the number of hours increases by 1, the dollars earned increases by $12.50. This increase in dollars earned is consistent across all increases in hours.

3. 4 gallons of milk for $13.16, 5 gallons of milk for $16.45, 9 gallons of milk for $29.61

If we check all of the options by multiplying the number of gallons by the given price per gallon, the following relationships are proportional to the original.
