6-1 Solving Systems by Graphing All solutions of a linear equation are on its graph. To find a solution of a system of linear equations, you need a point that each line has in common. In other words, you need their point of intersection. y=2x-1 The point (2, 3) is where the two lines intersect and is a solution of both equations, so (2, 3) is the solution of the systems..

6-1 Solving Systems by Graphing Example 2A: Solving a System Equations by Graphing Solve the system by graphing. Check your answer. -1 Y = -2x-3 Graph the system. The solution appears to Check be at (-1, -1). 1 21, 21} Substitute (-1, -1) into the system. y=-2x 3 (-1) -1 (-1) (-1) -1 -2(-1) -3 2-3 (-1, -1) is the solution of the system..
