A line graph uses points and lines on a grid to show change over a period of time.

How to make a line graph:
1. Use the data from the table to choose an appropriate scale. All scales start at 0.

2. Draw and label the scale on the vertical axis.
(Vertical means "up and down.")

3. Draw and label the horizontal axis. (Horizontal means "across.")

4. List the name of each item.

5. Locate the points on the graph.

6. Connect the points with line segments.

7. Write the title of the line graph.

Frank's Math Test Grades
Test	Grade
1	75
2	80
3	100
4	95
5	90
6	95

The data was organized in a table making it easier to read and interpret. The data from the table was used to create the following line graph.

A line graph is a graph that uses points and lines to show change over time.

What grade did Frank get on the third test?
First find test number 3 on the horizontal axis.

Then move up until you hit the point.

You see that Frank got a 100 on the third test.

A broken scale is used when the data starts at a large number.

Example:
