1. LINE GRAPHS HOW TO BE SUCCESSFUL WITH GRAPHING!

4. Parts of a Line Graph Vertical or y-axis Horizontal or x-axis points Connecting line 2 4 6 8 15 10 5 0 Value for the horizontal or x-axis (IV) Value for the vertical or y-axis (DV)

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.
