The Maths Prof: Finding Equation of a Perpendicular Bisector

In this lesson I show you how to find the equation of a perpendicular bisector of a line segment. ✨✨Steps to follow below✨✨
1. Find the gradient of the line AB
2. Find the gradient of the perpendicular bisector
3. Find the midpoint of the line AB
4. Find the y-intercept of the perpendicular bisector (using the midpoint coordinates and the gradient already found)
5. Write down the equation of the perpendicular bisector! 😊
