Question Analysis
This question tests the student's ability to determine if two lines are perpendicular by checking if the product of their slopes is -1. It requires understanding the condition for perpendicularity.

Key Concept Explanation
Perpendicular lines are lines that intersect at a right angle. The slopes of perpendicular lines are negative reciprocals of each other, meaning their product is -1.

Step-by-step Solution
1. Identify the slope of the first line: The equation of the first line is . The slope (m) is .
2. Identify the slope of the second line: The equation of the second line is
