Question

Marie requires 2 gallons of paint to cover an area of 400 square feet. Identify the graph that shows the relationship between the quantity of paint and the area covered and the parent function that best describes it. Then use the graph to estimate how many gallons of paint Marie requires to paint an area of 2,400 square feet.

Answer 1

Given:

x = 2 gallons of paint

y = 400 square feet of area

The graph representing the given point (x,y) = (2, 400) is number 4: linear 12 gallons.

Then, to estimate how many gallons of paint Marie requires to paint an area of 2,400 square feet.

We locate the point y = 2400 and find the corresponding x value. This is:

x = 12

Answer:

* the graph is the fourth one

* 12 gallons
