How do you write an equation for the perpendicular bisector of the line segment joining two points?
It is a pain in the … but here’s the general plan.
1. Calculate the slope of the segment.
2. Calculate the midpoint of the segment.
3. Determine the perpendicular slope by taking the negative reciprocal of the slope found in #1.
4. Use the point-slope form of a line, substituting the midpoint found in #2 and the perpendicular slope found in #3
