Interpreting Scatter Plots: Linear or Nonlinear Relationships

This lesson teaches how to interpret scatter plots by identifying if they are linear or nonlinear. Linear plots form a straight line, while nonlinear plots form a curve. Examples include comparing a square's side length to its perimeter (linear) and area (nonlinear), and a ball's height over time (nonlinear). The lesson emphasizes that not all real-world relationships are linear.

What happens to the perimeter of a square as the side length increases?

Describe a real-world example of a nonlinear relationship.
