A student is taking a test. There are 10 problems on the test. For each problem the student answers correctly, the student received 10 points. The graph shows the linear relationship between y, the points the student received on the test and x, the number of problems the student got correct on the test. Which set best represent the range for this situation?

• {0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10}

• {0, 10, 20, 30, 40, 50, 60, 70, 80, 90, 100}

• {0, 2, 4, 6, 8, 10}

• {0, 20, 40, 60, 80, 100}

Coach Parrish works a side gig as a security guard since he is so big and strong. He gets paid a flat fee of $200 and then $50 an hour after that. He works a maximum of 6 hours a shift. The cost for hiring Coach Parrish, y, to work x hours can be modeled by a linear function. What is the range of the function?

• {200, 250, 300, 350, 400, 450, 500)

• {0, 1, 2, 3, 4, 5, 6}
