About the Lesson

This lesson involves modeling relationship between variables related to the operational cost of airplanes.
As a result, students will:

• Find the line of fit to model relationship between airplane operational cost and other variables.
• Interpret slopes and y-intercepts in context of the data.
• Make predictions based on lines of fit for the given data.
