Chapter 19 Heart of Algebra focuses on the mastery of linear equations, systems of linear equations, and linear functions. The ability to analyze and create linear equations, inequalities, and functions is essential for success in...

This illustrated math lesson shows how important levels of accuracy in measurement are. The answer can be different since a scale only accurately weighs to the nearest tenth of a gram instead of to the nearest hundredth of a gram. Aligns...

The purpose of this task is to give students the opportunity to make connections between equations and the geometry of the graphs. Aligns with A-REI.C.7and A-REI.D.10.

[Free Registration/Login Required] This flipchart shows how to solve a system of equations using Cramer's Rule.

Twenty-seven problems present a variety of practice solving linear systems by substitution. They are given with each step to the solution cleverly revealed one at a time. You can work each step of the problem then click the "View...

This site provides a specific example of Cramer's Rule. The site does not explain why Cramer's Rule works, yet does a fair job of expressing the method to reach the answers.

A way to solve a linear system algebraically is to use the substitution method. The substitution method functions by substituting the one y-value with the other. This resource explains this method by showing an example along with a video.

[Free Registration/Login may be required to access all resource tools.] Recognize patterns of polynomials that are the product of two binomials.
