The ratio in which the line 3x - y + 6 = 0 divides the line joining the points A(3, 4) and B( 2, 1) is (A) 2:11(B) 9:2(C) 11:1(D) 1 : 12 |

Answer» Correct option (C) 11 : 1 Explanation : L ≡ 3x - y + 6 = 0, A = (3,4),B = (-2,1) L11 = 3(3) - 4 + 6 = 11, L22 = 3(-2) -1 + 6 = -1 Hence, the ratio AP : PB is -L11: L22 = (-11) : (-1) = 11 : 1 |
