Question Analysis
This question tests the student's understanding of the slope of perpendicular lines. The key concept is that the product of the slopes of perpendicular lines is .

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 if one line has a slope of , the slope of a line perpendicular to it is .

Step-by-step Solution
1. Identify the slope of the given line. The equation is in the form , where is the slope.
2. For the line
