Multiple Choice

What is the same about the two graphs showing the relationship between the time a water faucet has been on and the amount of water in a bucket?

• The relationship is exponential; more time results in less water.
• The relationship is quadratic; time has no effect on water amount.
• The relationship is linear; more time results in more water.
• The graphs show no relationship between time and water amount.

Multiple Choice

What is different about the two graphs showing the relationship between the time a water faucet has been on and the amount of water in a bucket?

• The rate of water flow from the faucet.
• The type of faucet used.
• The temperature of the water.
• The size of the bucket.

Multiple Choice
