Question

Geraldo gets paid the same amount for each hour he works. The graph shows the amount he is paid, y, as it relates to the number of hours he works, x. Yesterday, when he worked 6 hours, he was paid $84.
Geraldo’s Earnings
On a coordinate plane, a graph titled Geraldo's Earnings has number of hours on the x-axis and wages in dollars on the y-axis. The line goes through points (0, 0) and (6, 84).


Which ordered pair could represent the number of hours and amount Geraldo is paid today at the same hourly wage?
(3, 42)
(4, 60)
(5, 62)
(8, 100)

Answer 1

He earns $84 for 6 hours, so his hourly wage is 84 ÷ 6 = $14/hour.
Check each pair with y = 14x:

- (3, 42): 14 × 3 = 42 ✓
- (4, 60): 14 × 4 = 56 ✗
- (5, 62): 14 × 5 = 70 ✗
- (8, 100): 14 × 8 = 112 ✗

Answer: (3, 42).
