We can find the solution to a system of equations by graphing the equations Let s do this with the following systems of equations y 1 2 x 3 y x 1 First let s graph the first equation y 1 2 x 3 Notice that the equation is already in y intercept form so we can graph it by starting at the y intercept of 3 and then going up 1 Slope intercept form is easy though The equation for slope intercept form is y mx b In this equation m is the slope and b is the y intercept To graph a line from a slope intercept equation take the value of the slope and put it over 1 For example if the slope was 5 the slope would be 5 1

The steps for solving linear systems using the graphing method are outlined in the following example Example 4 1 2 Solve by graphing x y 4 2x y 1 Solution Step 1 Rewrite the linear equations in slope intercept form Try It 4 6 Solve the system by graphing 2x y 6 x y 1 In all the systems of linear equations so far the lines intersected and the solution was one point In the next two examples we ll look at a system of equations that has no solution and at a system of equations that has an infinite number of solutions
This is called solving by graphing and is a valid approach for linear equations with relatively simple slope and y intercept values The graphing systems of equations worksheets on this page fit this criteria and they are good practice for building a visual intuition of the solution process In practice it the linear equations in a system The first graph above being Case 1 in the left hand column shows two distinct non parallel lines that cross at exactly one point The corresponding system of equations is called an independent system and the solution is a single x y point Independent one intersection one solution Case 2 Case 3
