Match the graph to its function.  

The length (L) of a wall built in a day varies directly with the number of workers (W) on the job and inversely with the height (H) of the wall. If 5 workers can build a wall that is 6 feet tall and 20 feet long, what length of wall can be built with 6 workers that is 4 feet tall?

Solve x2 – x = 20 Enter your answers below, separated by a comma, no spaces. x = [xval]

A = (2, 5), B = (4, 1) and C = (6, -3). What is the midpoint of side BC?

Which of the graphs above matches the function given below? (Hint, even if you can’t see individual points, you should be able to match overall shape.)

These are the formulas you may need for the test:

The length (L) of a wall built in a day varies directly with the number of workers (W) on the job and inversely with the height (H) of the wall. If 8 workers can build a wall that is 6 feet tall and 20 feet long, what length of wall can be built with 11 workers that is 5 feet tall?

Determine the correct model (equation) for the following statement: “Weekly pay (P) varies directly with hours worked (H).”

A = (-2, 4), B = (4, 1) and C = (0, -2). What is the length of side AB?
