Line Graphs

A line graph displays data using line segments. Line graphs are mostly used to display data that changes over a period of time.


The table shows Russel's height at 3 -year interval. Make a line graph to display the data.

Age 3 6 9 12 15 18 21 24
Height (feet) 1.9 2.4 2.7 3 4.6 5.5 6.1 6.2

To draw a line graph, first draw a horizontal and a vertical axis. Age should be plotted on the horizontal axis because it is independent. Height should be plotted on the vertical axis.

Then look for the given data and plot a point for each pair of values. Draw a line connecting each pair of consecutive points. Then title the graph and label the horizontal and vertical axis.
