Proportional Relationships

Does the equation y = 1x represent the graph shown?

• Yes, because 2 divided by 2 equals 1, so the COP is 1.

• No, because the graph is not proportional.

A class is ordering custom T-shirts that cost $20 each. The total cost,
C (dollars), is proportional to the number of shirts ordered, s. Which equation represents this situation?

• n = 20C

• n = C + 20

• C = n + 20

• C = 20n

A skating rink charges $6.75 per person for admission. Since the total cost, C (dollars), is proportional to the number of skaters, n, which equation represents this situation?

• C = n + 6.75

• C = 6.75n

• n = C + 6.75

• n = 6.75C
