Does the graph show the system of equations x + y = 2 and −x + y = 7? Should the lines for the system be parallel?
A. The graph of −x + y = 7 is incorrect. The lines should be parallel.
B. The graph of x + y = 2 is incorrect. The lines should intersect.
C. Both graphs are correct. The lines should be parallel.
D. The graph of −x + y = 7 is incorrect. The lines should intersect.
