# Line Graphs - 3rd Grade & up

Definition: A line graph is a picture of a table of values. The table must have exactly 2 rows.

Of course, the table can have exactly 2 columns. In textbooks, we like rows because it saves space

Rule: Each point on the line graph is a column (2 pieces of data).

Here is a table of data with exactly two rows.

 Year 2001 2002 2003 2004 2005 2006 2007 2008 Apples on my Tiny Tree 3 4 6 7 7 3 5 7
Rule: The data in the top row goes horizontally to the right and the data in the bottom row goes vertically up the side.
 InterActivity   Directions for InterActivity In column B (Apples), double-click in a cell, type in a number between 0 and 10 and hit Enter. Check the line graph for changes. Make-up a "number of apples" for the year 2009. Where will this point be on the graph? Input the year 2009 (double-click on A10, type in 2009 and hit Enter). Input the number (double-click on B10, type in the number and hit Enter). Check whether the plotted point agrees with your thinking. Do this again for the year 2010.
