Given:
Line
To find:
Slope of the perpendicular line and slope of the parallel line.
Solution:
Equation of a given line:
Subtract 8x on both sides, we get
Divide by -6 on both sides.
Slope of this line is .
If two lines are perpendicular then their slopes are negative inverse of one another.
Slope of perpendicular line =
If two lines are parallel, then their slopes are equal.
Slope of perpendicular line =
