The graph below shows the total number of inches of rain that fell, y, in terms of time the rain fell, x.
The time is measured in hours after 12:00 P. M., with x=0 corresponding to the time 12:00 P. M.

Explain the meaning of the point (0,0) in the context of this problem.

Harold wrote this equation to model the level of water in a pool over time. the variable x represents time in hours. f(x) = 3,500 - 225x which statements about the situation are true? check all that apply. the water level is rising. the water level is falling. the initial level of water in the pool was 3,500 units. the initial level of water in the pool was 225 units. the pool was empty after 14 hours. the water was 2,600 units high after 4 hours.
