The two lines, a and b, are graphed below: line a is drawn by joining ordered pairs negative 3,18 and 9, negative 6. line b is drawn by joining ordered pairs negative 5, negative 2 and 8,17 determine the solution and the reasoning that justifies the solution to the systems of equations. (−4, 6), because both the equations are true for this point (2, 8), because the graph of the two equations intersects at this point (2, 8), because neither of the two equations are true for this coordinate point (−4, 6), because the graph of the two equations intersects the x-axis at these points
