Meaning
A line graph is a graph where you join the points with straight lines.
About Line Graphs
- Line graphs are used to show changes over time.
- Time is always plotted on the x-axis.
- Line graphs use x's to plot points on the graph.
- The variable that is being counted or measured goes on the y-axis.
Plotting a Line Graph
 |
 |
| Use the results table to find the highest number. (On this graph it's 8). | Days of the week is on the x-axis and number of vegetables on the y-axis. Add the numbers to the axes up the highest number. |
 |
 |
| Plot the points on the graph using an X at each point. | Join the X's with a line going from left to right. |
Examples
 |
 |
| 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. |
