Sophia: Solving Linear System by Graphing

The solution resides at the intersection. Pupils use a short instructional activity to review the process of solving a system of linear equations using graphing. The instructional activity provides completed graphs for most of the items,...

Lets keep the system working and show learners the three ways to solve linear systems of equations. Each method includes step-by-step instructions to work their way through the problem. The same problem is used for each method to show...

Sal teaches how to use graphing as a tool, not a hindrance, in this helpful video. His lecture would make be a good resource for your algebra class, particularly as the focus shifts to graphing problems and linear systems.

What happens when equations are multiples of each other? Pupils see the process of solving a system of equations by graphing. The informative video example shows two equations written in different forms that are actually the same line....

Another method for solving systems of equations, in addition to graphing, is the focus of this video, as Sal demonstrates the substitution method. It's important to understand that there is more than one way to solve any problem,...

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...

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...

The solution should satisfy each equation. Pupils view a helpful video showing an example of finding the solution to a system of linear equations by graphing. The presenter graphs the two lines to find the point of intersection and then...

This lesson demonstrates how to solve linear inequalities by graphing them on a coordinate plane. Includes short quiz. [8:36]

Substitution is a key concept in algebra—with many more uses than just solving linear systems. Build an integral foundational skill using a video tutorial and practice options in a well-designed lesson. The video offers multiple examples...
