The given lines are neither parallel nor perpendicular.
Explanation:
To check if two lines are parallel or perpendicular it is good to change the equations to form
The first line is:
The second line is:
From those equations we can see that those lines are **neither parallel nor perpendicular **
They would be parallel if the coefficients of
They would be perpendicular if the coefficients of
