Should the lines for the system be parallel? (1 point) Responses The 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. Both graphs are correct. The lines should be parallel. Both graphs are correct. The lines should be parallel. 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 statement is false, because the lines have an intersection point. The image shows that the lines y=−x+3 and x+y=8 intersect at the point (2, 6), which means that there is a solution to the system.

The correct response is "infinitely many solutions". By visually inspecting the equations, you can see that both equations have the same slope (-3/5) and the same y-intercept (-5), meaning they are the same line, and therefore have an infinite number of solutions.
