To determine the constant of proportionality from the given table, we can analyze the relationship between the number of buses and the number of people.
From the table:
- 1 bus accommodates 35 people.
- 2 buses accommodate 70 people.
- 3 buses accommodate 105 people.
- 4 buses accommodate 140 people.
The number of people is directly proportional to the number of buses. To find the constant of proportionality (k), we can use the formula:
\[ k = \frac{\text{Number of People}}{\text{Number of Buses}} \]
Let's calculate it for one of the entries, for example when there are 4 buses:
\[ k = \frac{140}{4} = 35 \]
This ratio (35 people per bus) appears consistently in the table and demonstrates that for each bus, there are 35 people.
Therefore, the constant of proportionality appears at the ordered pair (4, 140).
So, the final answer is:
(4, 140)
