Line Graph A graph that connects points to show how information changes over time. GLE 0406.5.1 0406.5.2 SPI 0406.5.1
Parts of a Line Graph Verticalor y-axis 15 10 5 0 points Value for the vertical or y-axis Connecting line Horizontal or x-axis 2 4 6 8 Value for the horizontal or x-axis
How to Make a Line Graph • Gather data. Line graphs will show specific changes in data. The data must have two comparable variables to use a line graph. • Label the horizontal or x-axis with the independent variable. This is the variable that can change. • Label the vertical or y-axis with the dependent variable This is the variable that won’t change. • Label each axis with a value and begin plotting your data. Draw a connecting line between each point.
Activity Example 1. Gather your data. For this example, data has been gathered about the average rainfall in TN. Degrees in Fahrenheit
2. Draw a right angle and label the horizontal and vertical axis. 5.15.04.94.84.74.64.54.44.34.24.14.03.93.83.73.63.53.43.23.13.02.92.82.72.6 Average amount of rainfall in inches for each month in Knoxville, TN Jan. Feb. Mar. Apr. May June July Aug. Sept. Oct. Nov. Dec. Months of the year
