Subject: Mathematics (9 - 12)
Title: Precalculus and Advanced Topics Module 2, Topic C: Systems of Linear Equations
URL: https://www.engageny.org/resource/precalculus-and-advanced-topics-module-2-topic-c-overview
Description:

Module 2, Topic C provides a third context for the appearance of matrices via the study of systems of linear equations. Students see that a system of linear equations can be represented as a single matrix equation in a vector variable and can be solved with the aid of the multiplicative inverse to a matrix if it exists.

Note: This module is identified as Precalculus and Advanced Topics in the EngageNY curriculum. It also corresponds to the Algebra II and Algebra II with Trigonometry Alabama Course of Study.
