A) Parallel
B) Coincident
C) Perpendicular
D) None of these
Correct Answer: A
Solution :
Given lines are not perpendicular i.e., \[a\ne -b\] Checking for parallel lines, \[\frac{a}{h}=\frac{h}{b}=\frac{g}{f}\] \[(3x+4y+6)(3x+4y+1)=0\Rightarrow \frac{9}{12}=\frac{12}{16}=\frac{21}{28}\] Hence lines are parallel.You need to login to perform this action.
