A system of linear equations has two or more equations that are graphed on the same coordinate grid. Begin graphing sequence one on y ≥ 2x + 3. The system is called independent if it has one solution. Graph each equation on the same graph. Because the point (1, 3) satisfies both the equations, the solution of the system is (1, 3). Graph y= (x-3)^2: y= (x-3)^2. Solve By Graphing One method of solving systems of equations is to carefully graph the equations on the same coordinate plane. Step 4: Check to make sure your solution makes both equations true. ) No Solution (Parallel Lines) Infinite Solutions (same line) Graphing Method Step 1: Graph the lines. First we recognize that the equations are in slope intercept form (y = mx + b) and that the slopes of each of the lines are different so we know that they will cross at some point. Any equation that cannot be written in this form in nonlinear. In systems of equations, the graphing method is solving x and y by graphing out the two equations.
