Middle schoolers factor and solve systems of equation. In this algebra lesson, students identify the point of intersection using substitution, elimination and graphing. They write an equation given a system and a graph.

Let's give parameters a second try. Scholars take a second look at a system of linear equations that involve a parameter. Using their knowledge of solutions of systems of linear equations, learners describe the solution to the system as...

In this systems of linear equations learning exercise, students graph two equations on each coordinate grid. All systems are linear. One of the systems is parallel. The others have one point of intersection.

Students solve systems of equations.  In this solving systems of equations lesson, students look for the intersection of the two lines in the system.  Students solve systems that have one solution, no solution, and infinite...

For this system of linear equations worksheet, students solve by using graphing, substitution, and elimination. There are 44 problems.

In this algebraic solutions worksheet, learners explore linear equations. They use algebra to solve linear systems of equations. This one-page worksheet contains ten problems.

In this linear systems learning exercise, learners solve systems of equations using three different methods: substitution, adding and subtracting, and graphing. This two-page learning exercise contains three multi-step problems.

Why do I have to learn two different ways to solve linear-quadratic systems? Isn't one way enough? Learners first investigate the three possible situations for linear-quadratic systems (two, one, or zero solutions), then solve such...

Ride to success in understanding systems of equations. Scholars graph a system of equations on the cost of a subway and a taxi using an interactive. Using this graph allows users to answer some questions about the situation.  

In this Algebra I/Algebra II worksheet, students use graphing to solve a system of linear equations.  The one page worksheet contains one multiple choice question.  Answer is included.

Pupils relate real life situation to the equations, graphs and inequalities. They model real life scenarios using matrices and draw conclusions from their data. This lesson plan is aligned with FCAT.
