Unit 4, Lesson 19# The Graph of Linear Equation in Two Variables Is a Line

EngageNY 45 min(s)

Students graph linear equations on the coordinate plane. Included in this and the next several lessons is an analytical approach to understanding linear equations and their graphs. For that reason, these lessons are structured to offer extensions (i.e., the proofs) in cases where students are ready and also to provide alternate activities that deepen conceptual understanding. The theorems are presented to students and, based on the readiness of each class, the teacher can choose to discuss the proof of the theorem, or students can explore the theorem experimentally by completing the exercises of the alternate activity.
