Number graph ranging from negative eight to eight on the x axis and negative eight to eight on the y axis. Two lines that are perpendicular to each other intersect at (three, zero). The line with a positive slope is labeled a and the line with a negative slope is labeled b. Use the graph to state the solution for the system. x – y = 3 (line a) x + y = 3 (line b)
A. (0, 3)
B. (–3, 0)
C. (0, –3)
D. (3, 0)
