The first step to solve this kind of questions is to write both equations in slope intercept form:
Now, we can determine whether they are parallel, perpendicular or neither.
For them to be parallel, they must have the same slope, but they don't, which means they are not parallel.
For them to be perpendicular, the product of their slopes must be -1, but it is not, which means they are not perpendicular.
The answer is that they are not parallel neither perpendicular.
