Use the image to answer the question.
A coordinate plane shows quadrant 4 with the x-axis, labeled as minutes, ranging from 0 to 6 in increments of 1 and y-axis, labeled as elevation in feet, ranging from 0 to negative 110 in decrements of 10. A ray with arrow at the bottom end points downward from the origin. The coordinates that it passes through are left parenthesis 0 comma 0 right parenthesis, left parenthesis 3 comma negative 60 right parenthesis, and left parenthesis 5 comma negative 100 right parenthesis.
The graph shows the elevation of a deep-sea diver in relation to minutes passed. Using any two points on the graph, what is the rate of change in the diver’s elevation?
(1 point)
feet per minute
To find the rate of change in the diver's elevation, we need to calculate the slope of the line connecting the two given points.
Let's choose two points on the line: (0, 0) and (3, -60).
The change in elevation is -60 - 0 = -60 feet.
The change in time is 3 - 0 = 3 minutes.
The rate of change is the change in elevation divided by the change in time: -60 / 3 = -20 feet per minute.
Therefore, the rate of change in the diver's elevation is -20 feet per minute.
