when solving a system of linear equation by graphing what determines the solution
The point where the two graphs cross is the solution.
If the graphs cross at the point (6, -5), then the solution is: x = 6 and y = -5.
If the lines are parallel, they don't cross and there is no solution.
If, when graphed, one line sits exactly on top of the other, then there is no single solution; every point is a solution to both equations.
