Big Ideas
- Understanding the connection between proportional relationships and linear graphs helps students make sense of the world using mathematics.
- The unit rate in a proportional relationship corresponds directly to the slope of its graph, allowing multiple representations of the same relationship.
Essential Questions
- How can you recognize a proportional relationship when it is represented graphically?
- What does the unit rate tell us about a real-world situation and how is it shown on the graph?
- How can you model a proportional relationship with a line, and what does the slope represent?
- Why is it important to be able to interpret the slope as a unit rate in a proportional situation?
- How do proportional relationships in tables or equations become lines when graphed?
