Answer 1

The constant of proportionality can be found by finding the ratio of the y-values to the x-values.

From the graph, we can see that the ratio of the y-values to the x-values is always 3/2.

Therefore, the constant of proportionality from the graph is 3/2.

2 beats per second

3 beats per second

Answer 3

To find the average number of heartbeats per second, we would need more information or data about the number of heartbeats over a specific time period. Without this information, we cannot determine the average number of heartbeats per second. Therefore, the correct response would be "Not enough information provided."
