Find the slope of the line that is perpendicular to the line represented by the equation y = 3x + 2

-3
3
1/3
-1/3

The correct answer is: -1/3

Perpendicular lines have slopes that are negative reciprocals of each other. Therefore, the slope of the line perpendicular to y = 3x + 2 would be -1/3. This eliminates options A and B as they have the same slope as the given line. Option C, 1/3, is the reciprocal of the slope of the given line, making it incorrect. Option D, -1/3, is the negative reciprocal of the slope, making it the correct answer.
