Objectives

Students will interpret points on the graph of a proportional relationship. Students will:

  • interpret points on a graph, which models a real-world proportional relationship. The points will include the origin and the unit rate.


Essential Questions

  • How is mathematics used to quantify, compare, represent, and model numbers?
  • How are relationships represented mathematically?
  • How can expressions, equations and inequalities be used to quantify, solve, model and/or analyze mathematical situations?


Vocabulary

  • Proportion: An equation of the form  that states that the two ratios are equivalent.
  • Ratio: A comparison of two numbers by division.
  • Unit Rate: A rate simplified so that it has a denominator of 1.
