Is the relation a function? Why.

• Yes, because the x-value 11 has two y-values pair with it.
• Yes, because each x-value has only one y-value paired with it.
• No, because the x-value 11 has two y-values pair with it.
• No, because each x-value has only one y-value paired with it.

Given the following ordered pairs, which coordinate will make this not a function?
(0, 3) (3, 5) (5, 6) (7, 7)

• (2, 3)
• (5, 8)
• (1, 1)
• (2, 7)

Brandt's car needed repairs. The mechanic charged him $240 for the parts and an additional $58 an hour for labor. How many hours of labor did the mechanic work on the car if his total bill was $327?  Which equation could be used to solve this problem?

• 240x + 58 = 327
• 240 + 58x = 327
• 327 + 58x = 240
• 327x + 58 = 240
