To determine the rate of change in the diver's elevation, we can choose any two points on the graph and calculate the slope (rate of change).
Let's choose the points (10, -100) and (30, 50) from the graph.
The first point (10, -100) represents 10 minutes past, with an elevation of -100.
The second point (30, 50) represents 30 minutes past, with an elevation of 50.
The slope (rate of change) can be calculated using the formula:
Slope = (change in y) / (change in x)
In this case, the change in y is 50 - (-100) = 150, and the change in x is 30 - 10 = 20.
Therefore, the slope (rate of change) of the diver's elevation is:
Slope = 150 / 20 = 7.5
The rate of change in the diver's elevation is 7.5 units per minute.
The graph shows the elevation of a deep-sea diver in relation to minutes past using any two points on the graph. What is the rate of change in the divers elevation?
