# Lesson 14

Using Linear Relations to Solve Problems

### Lesson Narrative

In this culminating lesson for the unit, students put what they have learned to work in solving real-world problems, using all the different forms of equations they have studied (MP4).

### 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.

### Student Facing

• I can write linear equations to reason about real-world situations.
