  2. 2 What is a graph? • A graph is a visual display of information or data. • Why use a graph? • It allows us to interpret information faster and easier than a data table.

  3. 3 Line Graphs • Line graphs are effective at showing a relationship where the dependent variable (DV) changes due to a change in the independent variable (IV). • The DV is placed on the y-Axis (vertical axis). The IV is placed on the x-Axis (horizontal axis).
