Solve Linear Systems of Equations: Graphing, Substitution, and Elimination

With 30 problems, each accompanied by a blank graph, pupils get thorough practice solving systems of equations by graphing and finding the point of intersection. Answers are provided in coordinate form.

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....

Which method of solving systems is the best? Individuals watch the same system solved using elimination, then substitution, and finally graphing. They can compare the different methods and see how each method results in the same solution.

After defining intercept, Sal solves a simple equation to identify each intercept and then plots the line on a graph. This video would quite nicely complement an introductory lesson on graphing.

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.

You've got a linear system of inequalities? You need to solve it by graphing? No sweat. Make sure that each equation is in slope-intercept form and then graph each equation. Is it a solid line or a dashed line? Which side of the line...

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

So many methods and so little time! The efficient method of graphing a linear equation depends on what information the problem gives. Pupils learn three different methods of graphing linear equations. They graph equations using...

Given verbal and/or algebraic descriptions of situations involving systems of linear equations, the student will solve the system of equations using graphs. Incorporates GeoGebra applets.
