Exploring Unit Rates on Graphs - The graph shows the rate at which paint is used to paint a wall.
Enter values to complete each statement below based on the graph.

1 gallon of paint will paint 400 ft² of the wall

Unit rate = 400 ft² per gallon

Step-by-step explanation:

From the graph, when 1 gallon of paint was used, (x = 1), an area of 400 ft² of the wall was painted (y = 400).

Unit rate = y/x. That is, the amount of square feet of wall that would be painted using 1 gallon of paint.

Unit rate = 400 ft²/1 gallon = 400 ft²/gallon.
