Making line graphs
Making line graphs to show change over a period of time is a straightforward process.
The title is " Scores on a basic math test" The scale is at the left of the graph. The distance between each square is 10, so the scale is 10 It shows scores for a student over a period of time or after taking 10 basic math test. A wealth of information can be deducted from the graph The lowest score is 40 and the highest score is 100 The greatest increase or improvement happened between test #2 and test #3. As you can see the student went from a score of 40 to a score of 70. The lowest decrease or happened between test #6 and test #7. The student went from a score of 90 to a score of 60 Looking at the graphs, it looks like although the score dropped a couple of times, overtime the student made consistent progress. Example: Use ther following data to make a line graph 
We get: 
The graph has an upward trend and shows that overtime, gas prices kept increasing. Looking at the graph, you can see that the line is steeper between 2007 and 2008. This means that the highest increase was experienced between 2007 and 2008. Gas prices went up by a dollar Types of graphs Bar graphs Making line graphs Circle graphs Home page
