A graph shows an x-axis representing time in seconds ranging from 0 to 12 in increments of 2. The y-axis represents heartbeats ranging from 0 to 18 in increments of 3. The graph shows a line representing resting heart rate.

The average number of heartbeats per second can be determined by finding the slope of the line representing the resting heart rate. Since the graph does not provide specific data points, it is not possible to accurately calculate the slope and determine the exact average number of heartbeats per second from the given information.
