Question

L et PQR be a right angled triangle isosceles triangle right angled at p (2, 1). If the equation of the line QR is 2x + 3y = 3 , then the equation representing the pair of lines PQ and PR is

(a) x + 3y = 5, 3x - y = 5 (b) x + y = 3, x -y = 1
(c) 3x + y = 7, 3x -2y = 4 (d) 3x + y = 7, x - 3y = -1
