Find the slope of a line perpendicular to the line y = –3x – 4.
Question
Find the slope of a line perpendicular to the line y = –3x – 4.
Solution
The slope of the given line y = -3x - 4 is -3.
The slope of a line perpendicular to a given line is the negative reciprocal of the slope of the given line.
The negative reciprocal of -3 is 1/3.
So, the slope of the line perpendicular to the given line is 1/3.
