=3 units Let the new lines drawn parallel to 3y - 4x - 15 = 0 be L1 and L2. Distance of L1 from origin = 3 + 3 = 6 units Distance of L2 from origin = 3 - 3 = 0 units The circle x2 + y2 = 25 has a radius of 5 units. Hence line segment of L1 lying inside the circle will be of zero length (L1 does not cut the circle). Chord cut by L2 will be diameter = 10 units
