(6 points) Find the equation for the plane P containing the points A = (1 , 3 , 1) , B = ( 3 , 1 , 3) , C = (5 , 2 , 2) . Solution: 2 x + y 3 z 2 = 0. b. (4 points) Find parametric equations for the line L through the points R = (1 , 5 , 3) and S = ( 2 , 6 , 2). Solution: The line is parallel to the vector v = 3 i + j k and passes through the point (1 , 5 , 3). So one choice of parametric equations is: x = 1 3 t, y = 5 + t, z = 3 t....
