Students will apply their knowledge of proportional relationships, equations, tables, and graphs to create a "pitch" to potential investors for their pizza parlor. This lesson builds on students’ work with graphing and constant of proportionality. Students will describe three points on a graph about pizza profits. Then they will use one of the points to write a pitch to potential investors. The mathematical concepts in this lesson build toward students’ future work with slope and writing equations in the form y=mx+b. Big Ideas: Each point on a graph relates the dependent and independent variables. Different points on a graph can be used for different purposes. Vocabulary: constant of proportionality, equation, dependent variable, independent variable
