Does the graph show the system of equations x+y=2 and −x+y=7? Should the lines for the system be parallel?(1 point)ResponsesThe graph of x+y=2 is incorrect. The lines should intersect.The graph of x plus y equals 2 is incorrect. The lines should intersect.The graph of −x+y=7 is incorrect. The lines should intersect.The graph of negative x plus y equals 7 is incorrect. The lines should intersect.The graph of −x+y=7 is incorrect. The lines should be parallel.The graph of negative x plus y equals 7 is incorrect. The lines should be parallel.Both graphs are correct. The lines should be parallel.

The graph of x + y = 2 and -x + y = 7 should be parallel because the slopes of the lines are equal and the y-intercepts are different.
