Given : Casey 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 +7, which represents the height of the slide at the pool  

To Find : What does 0 represent in this situation?

Answer 2

Answer:

Hello! I believe i have the answer and sorry if i was too late :(

Part A: The surface of the pool

Part B: The height of the slide is a postitive number in height, so, this means the height of the slide is above the starting point/surface of the water.

Part C: The bottom of the pole was at a depth of 2 feet. This means that Casey should mark the level of the bottom of the pole as -2 or negative 2. This is because it is IN the pool not ABOVE the pool. Or, it is rather under the surface and not above the surface.
