The equation of lines passing through point of intersection of lines 3x – y – 20 = 0 and x – 2y – 5 = 0, which are at a distance of 5 units from origin, is/are :
(A) 4x + 3y = 25
(B) 3x – 4y = 25
(C) 4x – 3y = 25
(D) 3x + 4y = 25
Correct option (C) (D)
Explanation:
points of intersection (7,1)
so line is y – 1 = m(x - 7)
