Chapter “13B” Systems of Linear Equations Lesson 13B.1 Solving Systems by GRAPHING Focus of lesson Systems of linear equations Solution of systems of equations Systems of Linear Equations A set of two or more linear equations in the same variables Example y 2x 5 y x2 Solution of a System of Linear Equation An ordered pair that is a solution in both equations. The solution is a point that the two lines intersect at. Types of Solutions (this will be covered in 13B.4) How to solve a system of equations by GRAPHING 1) Graph the line of each equation. 2) Estimate the point of intersection. 3) Check the point by substituting x and y in each equation.
