Middle Grades Math: Linear Modeling

by Texas Instruments


  • Students will use a moveable line to find a line of fit for a data set.
  • Students will interpret the slope and y-intercept of the equation of their line of fit.
  • Students will make predictions using their line of fit.


  • slope
  • y-intercept
  • line of fit

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.
