Big Ideas: Linear functions represent many real-world situations. The y-intercept of a linear function represents the initial value of a real-world situation. The slope of a linear function represents the constant rate at which the variables change together. This task builds on students’ understanding that functions are unique representations that explain the world around us (8.F.1) This is a culminating task that extends students’ knowledge of functions to include expenses and profits. It also contributes to their understanding that some real-life situations may be approximations and estimations. It builds a foundation for work with systems of linear equations and linear programming. Vocabulary: function, profit function, expense function, slope (rate of change), y-intercept (initial value) Special Materials: Supplemental Handout (price sheet)
