Two lines are given by the equations $$y = \frac{1}{2}x + 3$...

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.

Key Concept Explanation
Perpendicular lines intersect at right angles. The product of their slopes is -1.

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