Graphing Change Over Time 1. This table shows how the temperature in Boston changed
on one cold winter day. Make a line graph of the data.
Temperature in Bostonon Monday
Time Temperature in Fahrenheit

10:00 A.M. 5!
12:00 P.M. 9!
2:00 P.M. 10!
4:00 P.M. 8!
2. What do you think the temperature will be at 6:00 P.M.? Explain.
Possible answer: The temperature might go
down since the line from 2 P.M. to 4 P.M. went
down. I think that it might be 6! at 6:00 since
6! is less than 8!.
