The solution set is an infinite Set of ordered pairs representing the points on the line. 1. Solve each system by substitution. Is the system consistent, inconsistent or has dependent equations? a) 2 3 1 x y + = 2 y x ! = b) 2 1 x y + = 2 4 8 x y + = 2. Suppose you have $500,000 to invest, part at 15% and the remainder in a less risky investment at 6%.
