Lesson 2

Equations and Graphs

These materials, when encountered before Algebra 1, Unit 7, Lesson 2 support success in that lesson.

Lesson Narrative

In this lesson, students solve equations and graph them to see how the solution appears. In the associated Algebra 1 lesson, students solve quadratic equations by examining the graphs. The experience with linear equations in these activities will support students when they do the same work with quadratic equations in Algebra 1. Students reason abstractly and quantitatively (MP2) when they consider what parts of an expression are represented on a graph or in a situation.

Learning Goals

Teacher Facing

  • Interpret the meaning of solutions to linear equations in context.
