A) \( \Large x+4y=0\ and\ x+3y=0 \) |
B) \( \Large x+4y=0\ and\ x-3y=0 \) |
C) \( \Large x-6y=0\ and\ x-3y=0 \) |
D) \( \Large 2x-3y=0\ and\ x-4y=0 \) |
B) \( \Large x+4y=0\ and\ x-3y=0 \) |
Given equation can be rewritten
\( \Large x^{2}+4xy-3xy-12y^{2}=0 \)
Factorising the above equation we get
\( \Large \left(x+4y\right) \left(x-3y\right)=0 \)
Therefore separate equations for the lines are
\( \Large x+4y=0\ and\ x-3y=0 \)
