For this case we have the following system of equations: y = x + 5 y = -2x - 1 Substituting the point (-2, 3) we have: For Line C: y = x + 5 3 = -2 + 5 3 = 3 The line goes through this point. For Line D: y = -2x - 1 3 = -2 (-2) - 1 3 = 4 - 1 3 = 3 The line goes through this point. Answer: (-2, 3), because both lines pass through this point
