A line which is parallel to the line common to pair of lines given by 6x2 – xy – 12y2 = 0 and 15x2 + 14xy – 8y2 = 0 and makes intercepts on axes whose sum of length is 7,is
A
2x – 3y = 42
B
3x + 4y = 12
C
5x – 2y = 10
D
None of these
Answer
None of these
Explanation
Solution
lines given first equation are 2x – 3y = 0, 3x + 4y = 0 lines given second equation are 5x – 2y = 0, 3x + 4y = 0 hence required line is parallel to 3x + 4y = 0
