To find the slope of a perpendicular line, take the negative reciprocal of the slope of the given line. (Flip the top and bottom of the fraction and change the sign.) The slope of 3 can be written as 3/1. The slope of a line that is perpendicular is -1/3.

A perpendicular line has the negative reciprocal of the slope. The perpendicular line has a slope of 1/2 y=1/2 + 3 The 3 or y-intercept can really be any number though.

3x+y = 4 y = -3x+4 Perpendicular slope: 1/3

If a line has a slope m then a line perpendicular to it has a slope -1/m ( negative inverse). For example if a line has slope positive 2, its perpendicular has slope -1/2

Slope of the given line is 3/7 So slope of perpendicular line is -7/3

Slope of given line = -3 Therefore, slope of perpendicular = 1/3

Slope of given line = 3 So slope of perpendicular = -1/3

For the line 2x + y = 8 , the slope equals ( -2 ) so the required slope of the line which is perpendicular to it is equal to (+1/2 )

The line x = -4 is vertical, so a line that is perpendicular to it is horizontal, so its slope is 0.
