Learning Goals

Teacher Facing

  • Describe (orally) limitations of a graphical representation of a situation based on real-world constraints on the quantities.
  • Interpret the graph of a linear equation in context, including slope, intercept, and solution, in contexts using multiple representations of non-proportional linear relationships.

Student Facing

Let’s write equations for real-world situations and think about their solutions.

Learning Targets

Student Facing
