An art teacher has $80 to spend on museum tickets for her students. Admission tickets cost $10 per student. The graph shows the linear relationship between `y`, the amount of money remaining for tickets, and `x`, the number of students going to the museum.
The art teacher plans to spend all of the money on admission tickets. Which set best represents the
relationship between `x` and `y`?
A. {(0, 80), (1, 70), (2, 60), (3, 50), (4, 40), (5, 30), (6, 20), (7, 10), (8, 0)}
B. {(0, 80), (1, 70), (2, 60), (3, 50), (4, 40), (5, 30), (6, 20), (7, 10), (8, -10)}
C. {(10, 80), (20, 70), (30, 60), (40, 50), (50, 40), (60, 30), (70, 20), (80, 10), (90, 0)}
D. {(10, 80), (11, 70), (12, 60), (13, 50), (14, 40), (15, 30), (16, 20), (17, 10), (18, 0)}
