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...

Use this lesson plan to have students explore systems of inequalities.

[Free Registration/Login may be required to access all resource tools.] This lesson covers simplifying matrix expressions using all the previously learned matrix operations.

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

Students review matrix algebra. The resource consists of review exercises on the mathematics concepts.

The online quiz assesses student comprehension of math concepts. The quiz consists of true/false questions about matrix algebra.

The University of St. Andrews allows you to look through the history of matrices.

In this lesson, students can use the CBR ranger to model walking distance over time. They will walk away from the sensor, back towards the sensor and finally away from the sensor over an interval of 10 seconds. The result should be 3...

In this Computer Algebra System (CAS) activity, students investigate differential equations analytically, graphically and numerically and see relationships between the three approaches.

In this mini-instructional activity, we will explore the world of matrices by finding the answers to questions like how to solve systems of equations with matrices, how to solve matrices, and matrix operations with examples and formulas...

This site from the Richland Community College provides the detailed lecture notes to a college algebra course, complete with equations and definitions. Content ranges from "functions and their graphs" to "conics and parametric equations."

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.

Provides examples and a video lesson that illustrates how to use the elimination method to solve linear equations.

The primary focus in this activity is on parallel lines and equivalent equations. In Activity 1 and Activity 2, the class collectively will create a system of parallel and coinciding lines. It is important to focus on parallel lines...

This task has two separate goals: the first is to solve a pair of equations, one quadratic and the other linear. The second goal is to observe that a point that lies on a circle gives rise to a Pythagorean triple. Aligns with A-REI.C.7.

This comprehensive study guide highlights the main terms and formulas needed to review linear systems, specifically solving by graphing and substitution. Examples are included.

The purpose of this task is to test student skills at converting verbal statements into two algebraic equations and then solving those equations. Aligns with A-REI.A.1 and A-REI.C.

[Free Registration/Login may be required to access all resource tools.] Solve a system and use the result as a guide to identify its type.

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

Given the graph of a two-variable linear inequality, check whether a given pair of values is a solution of the inequality. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video, or...

[Free Registration/Login Required] This flipchart shows students how to solve systems of linear equations using elimination.

[Free Registration/Login may be required to access all resource tools.] Use their slopes to determine if two lines are parallel or perpendicular.

This question examines the algebraic equations for three different spheres. The intersections of each pair of spheres are then studied, both using the equations and thinking about the geometry of the spheres. Aligns with A-CED.A.2 and...

In this activity, students use Computer Algebra System (CAS) tools to find intersections of linear and non-linear equations. They confirm their answers by graphing the equations on the calculator.
