Line Graphs and Economic Data

CONTENT STATEMENT

14. Line graphs are used to show changes in data over time.

CONTENT ELABORATION

Use line graphs to display data that shows changes over time. Line graphs compare two variables. Each variable is plotted along an axis: an x-axis (horizontal) and a y-axis (vertical). Usually, the x-axis has numbers representing the time period and the y-axis has numbers for what is being measured. Change over time will be reflected by the peaks (ups) and valleys (downs) in the line.
Line graphs are useful in comparing economic data.

EXPECTATIONS FOR LEARNING
