A dolphin jumped from 5 feet below the surface of the sea. Jane wrote −5 to represent the depth from which the dolphin jumped. What does 0 represent in this situation?
the floor of the sea
the surface of the sea
the level to which the dolphin jumped
the level from which the dolphin jumped
If -5 means that the dolphin was 5 feet below the surface, then represents the surface of the sea. And, for instance, if the dolphin jumped 5 feet above the surface of the sea, 5 would represent that.
