The lines are
concurrent
Explanation for correct option
Option: Concurrent
For, lines to be concurrent
[From properties of determinants]
So, the lines are concurrent
Hence, the correct option is
Explanation for incorrect options
Option : Parallel
For lines to be the parallel lines, the slope of lines must be the same
Since,
Hence, the option is incorrect.
Option : Perpendicular
For lines to be perpendicular, the multiplication of slope should be equal to
Hence, the option is incorrect.
Hence, the only correct option is , so, the given lines are concurrent.
