Interpreting Graphs Objective:  To interpret graphs representing real life situations.

1.) The graph below models the relationship between time, in minutes, and the volume of water, in gallons, in a tub. What is the rate, in gallons per minute, at which the tub is being filled? A. 4 gallons per minute B. 14 gallons per minute C.5 gallons per minute D. 20 gallons per minute

2.) The graph below shows the distance, in miles, that the Campbell family drives on the first day of their vacation. What is the total number of hours that the Campbell family stopped during the first day?

3.) The graph below shows the number of new houses built in a town from 1970 to The mayor of the town used the graph to claim that between 1970 and 2000 the number of new houses built increased at a constant rate. Is the claim valid? A.It is valid because the graph shows a constant rate of change. B.It is valid because 30 years is long enough to evaluate the increase. C.It is not valid because the scale on the vertical axis is inappropriate. D.It is not valid because the scale on the horizontal axis is inappropriate.

4.) The graph below shows the height of a ball in one-second intervals. The curve of best fit has been drawn. According to the curve of best fit, what is the height of the ball at 4.5 seconds? According to the curve of best fit, when will the ball be at a height of 100 feet?

5.) Amy has a checking account at a bank. The graph below shows the relationship between the number of checks she writes and her monthly bank fees. If she writes 16 checks, what will be her monthly bank fee be, in dollars?

6.) The scatter plot below shows the relationship between the age and value of Judy’s car. A curve of best fit has been drawn. According to the curve of best fit, how much would Judy’s car have decreased in value when the car is 6 years old?

7.) The graph below shows Tanya's distance from home during the day. After leaving home at 8:00 a.m. when is Tanya at home again? A. between 9:00 a.m. and 10:00 a.m. B. between 11:00 a.m. and 12:00 noon C. between 1:00 p.m. and 2:00 p.m. D. between 3:00 p.m. and 4:00 p.m.

8.) The graph below shows the percentage of television-owning households with cable television. The line of best fit is drawn. Using the line of best fit, what percentage of television-owning households can be expected to have cable television in the year 2000?

9.) The graph below shows the average professional baseball salary from 1989 through Based on the graph, between which two years did the average salary have a negative rate of change? A to 1990 B to 1993 C to 1994 D to 1995

10.) The graph below shows the cost of a long-distance telephone call for various lengths of time. What is the cost of a 5 - minute long-distance telephone call?

11.) A family travels at a constant speed during a road trip. After 3 hours, they stop for 2 hours to eat and rest. They then continue for 4 more hours at the same speed. Which of these graphs best represents this situation? A. B. C. D. C. D.
