, 
- Components of the given point, dimensionless.
- Slope, dimensionless.
is the slope of the original line, dimensionless.
, and the slope of the perpendicular line is:
, 
and ![y-(-5) = \frac{5}{2}\cdot [x-(-3)]](/tpl/images/0737/9457/ca5e0.png)
- Slope, dimensionless.
.
, 
and 
, then:![y-1 = \frac{8}{5}\cdot [x-(-8)]](/tpl/images/0737/9457/8fbd1.png)
, and the slope of the perpendicular line is:
![y-1 = -\frac{9}{5}\cdot [x-(-8)]](/tpl/images/0737/9457/28dce.png)
