The graph does not show the system of equations x+y=2 and −x+y=7. The lines for the system should be parallel because the slopes of the two equations are the same (1), and the y-intercepts are different.

The dimensions of the graph are not clear, so it is not possible to determine the exact values of the intercepts.
