Part B: Connor says the graph shows that water is flowing at a rate of 2 gallons per minute. Is he correct? Explain.

• Connor is correct because the water is flowing in at a rate which is about 2 gallons per minute.

• Connor is not correct because the water is flowing in at a rate which is faster than 2 gallons per minute.

• 
  

  Connor is not correct because the water is flowing in at a rate which is slower than 2 gallons per minute.

• Connor is correct because the rate of water flowing is less than the slope.
