<em>Explanation: </em><em /><em />Since you are looking for a solution you need to look at the place where both lines connect, in this case, we are looking for the coordinate ( 2, -1 ) 2 being the x-axis and -1 being the y-axis The last graph is the only one that shows that the two lines touch at the coordinate ( 2, -1 )
The solution to a system of equations is the point on a graph where the two lines intersect. The graph where the point of intersection is (2, -1) is the last graph. The last graph is the correct answer.
