Jared measured the total height of the water in a bucket at different times during a rainfall. He displays his data using the graph shown. Select ALL the conclusions that Jared can correctly make using the graph.

• The height of the water in the bucket increases 1/2 inch every minute.

• The height of the water in the bucket increases at a rate of 3 inches per hour.

• In the first 20 minutes, the height of the water increases by 2 inches.

• It takes 60 minutes for the height of the water to increase by 4 inches.

• There is already 1 inch of water in the bucket when Jared places it outside.

This graph shows the population of the town of Golden Hills, modeled as a function of time since the town's found.

Match the description to the graph:

"The car is traveling at a constant speed."

What is a plausible description of this graph?

• The object began moving away quickly at a constant speed. It stopped. It then turned to return at a constant speed.

• The object changed diections three times.

• The object began walking away slowly then began running away. Both were at constant speeds. It then turned and walked back to where it started.

• The object began moving away at a constant speed. It continued moving away, but slowed its speed. It then turned around and returned home at a speed that was probably in between the first two speeds.

What is a plausible story for this graph?

• A student was jogging from school to home. She stopped to tie her shoe and take a drink from her water bottle, then continued at the same pace as before.

• A student was jogging from school to home. She walked for a while, then continued jogging.

• A sled rider was going down a hill. The hill was steep at first, then kind of flat. At the end, it was steep again.

• A car was slowing down, then contued moving at a constant rate. Finally, it slowed to a stop,
