The graph shows two lines, A and B. A coordinate plane is shown. Two lines are graphed. Line A has equation y equals negative 3 x plus 15. Line B has equation one half x plus 2. Based on the graph, which statement is correct about the solution to the system of equations for lines A and B? (4 points) a (4, 4) is the solution to line A but not to line B. b (4, 4) is the solution to both lines A and B. c (5, 1) is the solution to line B but not to line A. d (0, 2) is the solution to both lines A and B.
