To find the constant of proportionality from the table, we need to determine the ratio of the number of people to the number of buses.
According to the table:
- For 1 bus: 35 people → Ratio: 35/1 = 35
- For 2 buses: 70 people → Ratio: 70/2 = 35
- For 3 buses: 105 people → Ratio: 105/3 = 35
- For 4 buses: 140 people → Ratio: 140/4 = 35
The constant of proportionality is consistent at 35 people per bus.
The ordered pair representing this ratio, which corresponds to 1 bus and 35 people, is (1, 35).
So the answer is:
(1, 35)
