Students will apply their knowledge of y=mx+b to graph the monthly salaries of four different jobs. The activity offers a choice of giving the job descriptions on task cards or at the top of the graphing worksheet.
Students will work together to understand and graph the salaries (each with a different y-intercept based on a signing bonus or start-up cost), then they will answer questions about the salaries earned over time.
This is a great activity for exploring linear functions, relating and expanding on current understanding, and as ground work leading up to solving systems. This activity can be re-visited as new skills are introduced.
Includes key. Allow at least 30-40 minutes to complete. Then more time for discussion as needed. Students should have some understanding of y=mx+b before doing this activity.
Key Terms: Linear Functions, Graphing Lines, Application, Real World, Function Rule, Slope Intercept Form of a Line.
Perfect for Common Core exploration and concept building.
