At the beginning of summer, a maintenance crew refills a swimming pool at a city park. The relationship between the time in hours to fill the pool and the amount of water in the pool is proportional. After 4 hours, the pool holds 5,200 gallons of water. Answer parts a and b. a. How could you graph this relationship? A. Plot the points (0,4) and (0,5200). Draw a line through these points. B. Plot the points (0,0) and (4,5200). Draw a line through these points. This is the correct answer. C. Plot the points (0,4) and (5200,0). Draw a line through these points. D. Plot the points (4,0) and (0,5200). Draw a line through these points. Your answer is not correct. b. The same crew refills a second pool as represented by the graph shown. Is the second pool filled at a faster or a slower rate than the first pool? Explain. The unit rate for the first pool is ▼ nothing gallons per hour. The unit rate for the second pool represented by the graph is ▼ StartFraction 10 comma 800 ga l l ons Over 3 hours EndFraction StartFraction 3 hours Over 10 comma 800 ga l l ons EndFraction StartFraction 3 ga l l ons Over 10 comma 800 hours EndFraction StartFraction 10 comma 800 ga l l ons Over 1 hour EndFraction nothing gallons per hour. So, the second pool is filled at a ▼ slower faster rate.
