Solving Systems of Equations by Graphing
Solving systems of equations by graphing is super easy. All you do is to graph each equation and find the point where the intersect (or touch each other). Most of the time, your answer will be a point that give both an x and y value. Be aware that it is possible to get parallel lines that never touch (no solution) or to get identical lines (many solutions). |
