# What is the perpendicular bisector of a line with points at A #(-33, 7.5)# and B #(4,17)#?

##### 1 Answer

Equation of perpendicular bisector is

#### Explanation:

Let us use point slope form of equation, as the desired line passes through mid point of A

This is given by

The slope of line joining A

Hence slope of line perpendicular to this will be

Hence perpendicular bisector will pass through
