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.
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.
