Exercise 4.2 (page 157) 1. Plot the following points: A(2,−2), B(−2, 1), C(−1, 0), D(0,−2). 2. State the coordinates of the points U, V and W . 3. A point P lies on the x axis. State the y coordinate of P. 4. A point Q lies on the y axis. State the x coordinate of Q. Ans: 1. We have points: A(2, -2) , B(-2, 1) , C(-1, 0) , D(0, -2) 2. State the coordinates of the points : U(−2,−2), V(4, 1), W(3,−1) 3. A point P lies on the x axis. State the y coordinate of P. P(0, 0) 4. A point Q lies on the y axis. State the x coordinate of Q. Q(0, 0) Exercise 4.3 (page 158) 1. Plot the points A(2, 0,−1), B(1,−1, 1) and C(−1, 1, 2). 2. State the equation of the plane passing through (4, 7,−1), (3, 0,−1) and (1, 2,−1). 3. State the equation of the plane passing throu...
