Line Graphs

Example:

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.
