Are the following two lines Parallel, Perpendicular, or Neither and WHY? Select the correct answer choice below.

In this case, we'll have to carry out several steps to find the solution.
Step 01:
Data
Parallel, Perpendicular, or Neither = ?
Step 02:
We must analyze the lines to find the solution.
The lines intersect at a 90 degree angle.
Therefore, the lines are perpendicular.
The answer is:
Perpendicular, because the slopes are opposite and reciprocal.
