Given parameters:
Equation of the line is y = - + 8
Unknown:
Slope of line parallel to this line = ?
Slope of line perpendicular = ?
Solution:
A line parallel to this line will have the same slope with it.
A line perpendicular will have the negative inverse of this slope;
Slope of line = -
Slope of line parallel to this line =
Slope of line perpendicular = negative inverse = -( -()) = 2
So, the slope of line parallel to this line is - 1/2 and that perpendicular is 2
