    when you graph them, the intersections of those lines becomes the point that is on both lines. which basically means that that intersection point satisfy both of those equations. that means that the pair of numbers of the intersection point is the answer to the system of equation. so if you need to solve it by graphing, you need to graph it precisely using a graphing paper or a calculator.
