Using multiple representations to analyze and to evaluate problem situations helps students to see how the linear function in all forms. Students are given one of three problem situations in 3D: table, graph or verbal description. In the tables, students are asked to identify the domain and range; determine if the pattern is linear and explain; calculate the slope and write an equation in slope-intercept and standard forms; calculate the y and x-intercepts. Also, students are given a group of tables and are asked to compare and contrast the slopes of the cars. Use the graph to determine the amount of water in the swimming pool and the problem situations to determine the balance left after they pay off the account.
