A comprehensive guide for learning all about linear equations in two variables with definitions, how to solve them, solved examples, and practice questions.

[Free Registration/Login may be required to access all resource tools.] Given a set of constraints, graph and solve linear problems.

Demonstration of how an augmented matrix is used to solve a system of linear equations.

The name linear comes from the fact that such an equation in two unknowns or variables represents a straight line. A set of such equations is called a system. This site explains all this and more.

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...

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.

This Computer Algebra System (CAS) activity encourages students to investigate addition, subtraction, and multiplication of matrices. They find the inverse of a matrix. Students also solve a set of linear equations by using matrices.

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

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.

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 mini-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 while...

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."

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

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.

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.

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.
