The intersection point $(x,y)$ of the two lines.

Work Step by Step

We understand that a point $(x,y)$ on a line will satisfy the equation for that line; thus the intersection point of two lines will satisfy the equations of both lines. In other words, solving by graphing both linear equations, we can determine the solution by locating the intersection point $(x,y)$ of the two lines.
