Some children played in their kiddie pool on Tuesday. They splashed some of the water out. On Wednesday, their dad uses a garden hose to re-fill pool. Part of the graph is shown to show the relationship between the volume of water in the pool and the time the garden hose is on. The domain of the scenario is 0-20 minutes.
Graph the rest of the line.

What is the vertical intercept of the line that?
models the relationship between the volume
of water in the pool and the time the garden
hose is on?

What does the vertical intercept mean in context?

What is the rate of change?
