Question Analysis
This question tests the student's understanding of the condition for perpendicular lines. The key concept is that two lines are perpendicular if the product of their slopes is -1.

Key Concept Explanation
Perpendicular lines have slopes that are negative reciprocals of each other. The product of the slopes of two perpendicular lines is -1.

Step-by-step Solution
1. Identify the slopes of both lines. For the first line, the slope is .
2. For the second line, the slope is
