A) Lines are parallel
B) Lines are coincident
C) Lines are intersecting
D) Lines are perpendicular
Correct Answer: C
Solution :
Let \[{{L}_{1}}\equiv 2x+5y-7=0\] and\[{{L}_{2}}\equiv 2x-5y-9=0\], so that\[{{m}_{1}}=-\frac{2}{5},{{m}_{2}}=+\frac{2}{5}\]. Lines are neither parallel nor perpendicular, also not coincident. Hence the lines are intersecting.
