The ratio in which the line 3 x+4 y+2=0 divides the distance between 3 x+4 y+5=0 and 3 x+4 y-5=0 , is
Options
- A7: 3
- B3: 7
- C2: 3
- DNone of the above
Correct answer
B. 3: 7
Step-by-step solution
Since, the lines 3 x+4 y+2=0 and 3 x+4 y+5=0 are on the same side of the origin. The distance between these lines is 5-2=3 . And the line 3 x+4 y+2=0 and 3 x+4 y-5=0 are opposite side of the origin, The distance between these lies is 7 . Hence, required ratio is 3: 7 .
