Chapter 3, Problem 55(choose chapter or problem)
Let P be a point with coordinates (a, b), and assume that c and d are positive numbers. (The condition that c and d are positive isnt really necessary in this problem, but it will help you to visualize things.) (a) Translate the point P by c units in the x-direction to obtain a point Q, then translate Q by d units in the y-direction to obtain a point R. What are the coordinates of the point R? (b) Translate the point P by d units in the y-direction to obtain a point S, then translate S by c units in the x-direction to obtain a point T. What are the coordinates of the point T? (c) Compare your answers for parts (a) and (b). What have you demonstrated? (Answer in complete sentences.)
