Name: ID: 3. (10 points) (a) (6 points) Give an equation (11-1110 plane through the points P : (1, 11 1), Q : [1, l, 1) and R : (l. 71.71]. (b) (,1 points) Calculate the point of intersection between this line r[) = (0.3.2) + t(1. 2. n) and the plane containing P. Q and R. Dr Show that no point of intersection exists
