4 (b) The line / has equation r=-5+ a 3 The line 12 has equation r = -8-8 The point P lies on ₁ where a = -1. The point Q lies on 12 where ß = 2. (i) H (ii) (iii) Show that PQ is parallel to (4 marks) The ₁ and 2 intersects at the point R (3, b, c). Show that b value of c. (4 marks) The point S lies on a line through P that is parallel to 12. The line RS is perpendicular to line PQ. Calculate the position vector of S. (5 marks) 12 = -2 and find the
