Given

First, we need to calculate the slope of the given points

Next, we determine the slope of the perpendicular bisector using:

Next, is to determine the coordinates of the bisector.

To bisect means to divide into equal parts.

So the coordinates of the bisector is the midpoint of the given points;

So, the coordinates of the midpoint is:

Equation in form is:

Substitute values for y1, m and x1: &
