Janice was at the surface of a swimming pool and recorded the following two measurements, in feet, on a number line:

−8, which represents the depth of water in the swimming pool
+12, which represents the height of the slide at the pool

Part A: What does 0 represent in this situation? (3 points)

Part B: Describe the height of the slide in relation to 0 in the situation. (3 points)

Part C: Janice held a pole in the swimming pool. The bottom of the pole was at a depth of 4 feet. How should Janice mark the level of the bottom of the pole on the number line? Explain how you determined this. (4 points)

PLEASE HELP

Given two reference points, we want to answer some questions, the answers are:

  • a) The 0 should represent the surface of the water of the pool.
  • b) The slide is 12 ft above the zero (12ft above the surface of the water)
  • c) She should mark the pole with a -4 on the number line.

So we start with two reference points:

  • -8, which represents the depth of water in the swimming pool.
  • 12, which represents the height of the slide at the pool.

So positive numbers represent height, negative ones represent depth.

A) Here the 0 should represent the surface of the water of the pool.

B) on this situation, we should see that the slide is at 12, meaning that is 12 ft above the surface of the water in the pool.

C) The pole is at a depth of 4 ft, and 0 represents the surface, then -4 will represent the depth of the pole when it is at a depth of 4 ft. She must mark the level of the pole as a -4 on the number line.
