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?

Answer 1

wrong

Answer 2

To find the rate of change in the diver's elevation, we can use the formula for slope:

Slope = (y2 - y1) / (x2 - x1)

Let's choose the points (0, 0) and (5, -100) to calculate the rate of change:

Slope = (-100 - 0) / (5 - 0)
Slope = -100 / 5
Slope = -20

Therefore, the rate of change in the diver's elevation is -20 feet per minute.

Answer 3

I apologize for the mistake. Let's choose the points (3, -60) and (5, -100) to calculate the rate of change:

Slope = (-100 - (-60)) / (5 - 3)
Slope = (-100 + 60) / 2
Slope = -40 / 2
Slope = -20

Therefore, the rate of change in the diver's elevation is -20 feet per minute.
