Does that graph show the system of equations x+y=2 and -x+y=7? should the lines for the system be parallel?
the graph of -x+y=7 is incorrect. the lines should intersect.
the graph of x+y=2 is incorrect. the lines should intersect.
the graph of -x+y=7 is incorrect. the lines should be parallel.
Both graphs are correct. the lines should be parallel.
