Graphing equations is a much simpler process that most people realize You don t have to be a math genius or straight A student to learn the basics of graphing without using a calculator Learn a few of these methods for graphing linear quadratic inequality and absolute value equations Here is a general method for solving equations by graphing Step 1 Let y be equal to the expressions on both sides of the equal sign Step 2 Graph the two functions that were created Step 3 Approximate the point s at which the graphs of the functions intersect
When solving systems of linear equations one method is to graph both equations on the same coordinate plane The intersection of the two lines represents a solution that satisfies both equations Other more mathematical methods may also be How to solve System of Equations by Graphing To solve systems of equations or simultaneous equations by the graphical method we draw the graph for each of the equation and look for a point of intersection between the two graphs The coordinates of the point of intersection would be the solution to the system of equations

How to solve systems of equations by Graphing Step by step tutorial for systems of linear equations in 2 variables Table of contents top Example Practice Problems Systems of Linear Equations Worksheets What is a System Interactive System of Linear Equations Video on Solving by Graphing The method we used at the start of this section to graph is called plotting points or the Point Plotting Method Let s graph the equation y 2 x 1 y 2 x 1 by plotting points We start by finding three points that are solutions to the equation We can choose any value for x x or y y and then solve for the other variable
How do we use graphs to solve equations Solutions are always read off the x axis Solutions of f x 0 are where the graph of y f x crosses the x axis If asked to use the graph of y f x to solve a different equation the question will say something like by drawing a suitable straight line then Solve a System of Linear Equations by Graphing In this chapter we will use three methods to solve a system of linear equations The first method we ll use is graphing The graph of a linear equation is a line Each point on the line is a solution to the equation For a system of two equations we will graph two lines
