Temperature is the dependent variable because it varies with time. Graph time on the x-axis and temperature on the y-axis. Mark equal increments on the graph and include all measurements. Plot each point on the graph by finding the time on the x-axis and moving up until you find the recorded temperature on the y-axis. Continue placing points on the graph. Then, connect the points from left to right.

Time	Temp
8:00 A.M.	27°C
12:00 P.M.	32°C
4:00 P.M.	30°C

  

Solve the Problem

1. Based on your graph, what was the temperature at 10:00 A.M.? What was the temperature at 2:00 P.M.?

2. What is the relationship between time and temperature?

3. Why is a line graph a useful tool in viewing this data?

4. For what other types of data might a line graph be useful?
