How to Make a Line Graph
1.Gather data. Line graphs will show specific changes in data. The data must have two comparable variables to use a line graph.
2.Label the horizontal or x-axis with the independent variable. This is the variable that can change.
3.Label the vertical or y-axis with the dependent variable This is the variable that won’t change.
4.Label each axis with a value and begin plotting your data. Draw a connecting line between each point.
1. Gather your data. For this example, data has been gathered about the average rainfall in TN.
