About Line Graphs

Line graphs are used to show changes over time.
Line graphs use x's to plot points on the graph.
Time is always plotted on the x-axis.
The variable that is being counted or measured goes on the y-axis.

The day of the week is plotted on the X-axis, the number of minutes spent watching TV each day is plotted on the y-axis. The Time of Day is plotted on the x-axis and the temperature is plotted on the y-axis.
