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
