This module was designed and written to help you gain an understanding of and to test your ability in interpreting data presented in different kinds of line graphs. Remember that a line graph is a rectangular coordinate system consisting of the x and y axes.
Line graphs allows us to easily see changes in the values of the variables as well as trends, if there are any. So, what are you waiting for? Stay focused and go.
At the end of this module, you are expected to be able to:
- identify the kinds of line graphs;
- appreciate the importance of line graph labels; and

Before going any further, let us check your understanding of and your skills in interpreting data presented in different kinds of line graphs.
