The slope of the perpendicular is -(1/2) .
No, the two lines are not perpendicular.
10 is.
Slope of given line = -3 Therefore, slope of perpendicular = 1/3
negative 1
It is: 1/5
The second equation works out as y = -1/2x+6 therefore it is perpendicular
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 )
45
0909
It is: minus 1.25
-5/3
