Use the image to answer the question.

A Cartesian coordinate plane graph displays two parallel lines.

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)

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.

The graph of −x + y = 7 is incorrect.

x + y = 2 gives y = −x + 2 (slope −1). −x + y = 7 gives y = x + 7 (slope 1). The slopes are different, so the lines should intersect (e.g. at (−2.5, 4.5)), not be parallel.
