The graph shows the relationship between a volume measured in quarts (x) and its corresponding measure in gallons (y).

What is the slope of this line? Interpret this value in the context of this problem.

• The slope is 0.25. This means that for every 1 quart, there are 0.25 gallons.

• The slope is 4. This means that for every 1 quart, there are 4 gallons.

• The slope is 0.5. This means that for every 1 quart, there are 0.5 gallons.

• The slope is 2. This means that for every 1 quart, there are 2 gallons.
