Slope = 2
The slope of the line of 2x plus 2y equals 7 is (7/2x - 1).
The slope of the perpendicular is -(1/2) .
The slope is -1 .
Slope of given line = -3 Therefore, 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 )
It is: 1/5
After solving for y you will get y=1/5 x+1. The slope of this line is 1/5.
line in data is y=-2X+6 The perpendicular line will have a slope of = +1/2 Note : m X m' = -1 , m= slope of line 1 ; m'= slope of perpendicular line to line 1
