8. 7 X-axis and Y-axis When you are making a line graph, the x-axis is always horizontal, and the y- axis is always vertical.

9. 11/23/20158 Plotting a Line graph When we are plotting a line graph, it is important to put a label on each axis that describes the information Time in minutes

10. 11/23/20159 NUMBERS - SCALE When we are setting up a line graph, we need to decide what intervals we want to use. We want the graph to be as big as possible, so the scale should go from 0 to about our maximum number.

11. 11/23/201510 Answer the questions: What is on the x-axis? Year OR # of individuals What is on the y-axis? Year OR # of individuals What is the scale on the y-axis? What is the interval value on the y-axis? Does this graph need a key? 0 to 8000 No, only 1 line 1000

12. 11/23/201511 Is this an acceptable graph? Time Car Trip

13. 11/23/201512 What information do you need to interpret a graph? The graph we just looked at does not have any numbers on the x-axis or the y- axis. Can we still draw conclusions and answer questions about that graph? How many times did the driver stop driving during the trip? Time Car Trip X and Y axis scales!!

14. 11/23/201513 Practice With Graphs Please study the graphs that you have and answer the questions. Then we will discuss the your answers.
