Slope of a line perpendicular to x-y=16
The slope of the perpendicular is -(1/2) .
Slope of given line = -3 Therefore, slope of perpendicular = 1/3
Slope of the given line is 3/7 So slope of perpendicular line is -7/3
Slope of given line = 3 So slope of perpendicular = -1/3
The line x = -4 is vertical, so a line that is perpendicular to it is horizontal, so its slope is 0.
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 slope is -0.2
