For this case, we have that by definition, if two lines are perpendicular, it follows that:
If we have the line:
With slope
A line perpendicular to this would have slope:
Thus, the equation of this line is given by:
Substituting the pointwe find the cut point "b":
Thus, the equation is:
Multiplying by "3" on both sides of the equation:
