Modelling with linear graphs via a real life situation. What is the better option when buying a car on instalment? Practice sketching linear graphs, solve simultaneous equations, compare the two options graphically and algebraically. Interpret graphical and algebraic solutions.

 Have students analyze the graph and draw conclusions.
 Ask questions like, “How many months will it take to pay off the car?” or “What’s the total amount paid in installments?
 Discuss the importance of understanding installment plans when making financial decisions.
 Explore variations, such as changing the down payment or interest rate, and see how they affect the graph.
 Provide practice problems for students to create linear equations and graphs for different car purchase scenarios.
 Encourage them to calculate the total cost of the car over time.
