Solving Systems of Linear Equations by Graphing - Part 1

Get hands on with solving systems of equations graphically. A solid lesson plan uses guided practice to show how to solve systems of linear equations. It allows time for sharing ideas and provides a printable matching activity...

Expand on learners' understanding of quadratic-linear systems. Building on the graphic understanding developed in the previous lesson, pupils learn algebraic methods of solving the systems. 

Solving systems of equations underpins much of advanced algebra, especially linear algebra. Developing an intuition for the kinds and descriptions of solutions is key for success in those later courses. This intuition is exactly what...

Sal evaluates a word problem and then solves by graphing systems of equations. This problem would be great as a daily challenge, as concept review, or as a homework assignment. Show this video only after the students have had a chance to...

If your class has a grasp on the concept of graphing systems of equations and has worked inequalities, then it's time to expose them to the wonders of graphing systems of inequalities. Using various colors and a graph, Sal explains what...

Sal uses the elimination method to simplify a system of three variables. Next, he employs the substitution method to check his solution. This resource would nicely complement any lesson on this topic.

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...

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...

Systems are meant to be solved. An educational video teaches scholars how to graph systems of linear equations to determine whether they have one solution, no solution, or many solutions. They also see how to graph systems of equations...

Solve equations and graph systems of inequalities. Designed as a lesson to reinforce these concepts, learners revisit shading and boundaries along with solving linear inequalities.
