Question

In the previous activity, you found an equation with a negative unit rate, y = -50x – 100. This equation gave the depth of a submarine, y, given time, x. It assumes that the submarine starts at a depth of 100 feet, and then starts descending at a rate of 50 feet per minute. In this activity, you will graph the equation.

Part C
The line formed by this equation lies in several quadrants on the graph. In which quadrant specifically does the equation describe the submarine’s movement? Why only this quadrant?

Answer 1

Answer:The submarine starts at a negative elevation: 100 feet below sea level. It then dives downward. So, the submarine is always at a negative elevation. But the time from the start of the dive will always be positive. So, the part of the line that models this situation lies in quadrant IV.
