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. If 1 gallon of paint has been used, then 400 square feet of the wall will be painted.

2. The unit rate is 400 square feet per gallon.

Step-by-step explanation:

In the given graph x-axis represents the paint used in gallons and y-axis represents the painter area in square feet.

From the given figure it is clear that line passes through the point (1,400) it means if 1 gallon of paint has been used, then 400 square feet of the wall will be painted.

If a line passes through two points and , then the unit rate of line is

From the given graph it is clear that the line passes through the points (0,0) and (1/4,100). It So the unit rate is

The unit rate is 400 square feet per gallon.
