Linear Systems: Matrix Inverse

Introduce the inverse matrix method to solve systems of linear equations both algebraically and graphically. Using given data, your class checks their answers with graphing calculators. Handouts are included in this well-thought out...

Learners must think critically about the graphical and algebraic forms of a system of linear equations in order to come up with their own system when given a point that is the solution to the system.

Examine the usefulness of matrices when solving linear systems of higher dimensions. The lesson asks learners to write and solve systems of linear equations in four and five variables. Using matrices, pupils solve the systems and apply...

Picture the solution. The Mathispower4u Algebra I video uses three examples of finding the solution of a system of linear equations given as a graph. Pupils use their knowledge of linear graphs to also identify the equations for the...

Determine the geometric representation to the solution of a system of linear equations. The resource shows how scholars can represent a system of linear equations as a linear transformation. The video discusses using an inverse...

Provide a consistent and independent example. Pupils watch an algebra video showing how to find a solution to a system of linear equations by graphing. The presenter graphs the two linear equations to find the one solution to the system...

Solve a pretty straightforward system. Pupils view an educational video showing how to solve a system of linear equations by graphing. The system consists of a horizontal line and a vertical line, making the solution apparent in the...

Let the technology do the graphing. Learners watch a helpful algebra video that shows how to use a graphing calculator to solve a system of linear equations. The presentation works through one example using a TI-84 to solve a system and...

In a system of linear equations, the solution must satisfy each of the equations to be true. Thus, in a system of linear inequalities, the solution must satisfy each of the inequalities to be true. This is a short video that defines what...

Two of the strategies for solving systems of linear equations are represented in this foldable: substitution and elimination. Learners solve three examples of each.
