<h3>What is a perpendicular bisector of the line segment?</h3>
A perpendicular bisector is a line that cuts a line segment connecting two points exactly in half at a 90 degree angle. To find the perpendicular bisector of two points, all you need to do is find their midpoint and negative reciprocal, and plug these answers into the equation for a line in slope-intercept form.
Given that,
Endpoints of the line segment are (
) = (4, 1) and (
) = (2, -5).
First find the midpoints of the given line segment.
M = ![\left(\frac{x_{1}+x_{2} }{2},\frac{y_{1}+y_{2} }{2}\Right)](https://tex.z-dn.net/?f=%5Cleft%28%5Cfrac%7Bx_%7B1%7D%2Bx_%7B2%7D%20%20%7D%7B2%7D%2C%5Cfrac%7By_%7B1%7D%2By_%7B2%7D%20%20%7D%7B2%7D%5CRight%29)
= ![\left(\frac{4+2 }{2},\frac{1-5 }{2}\Right)](https://tex.z-dn.net/?f=%5Cleft%28%5Cfrac%7B4%2B2%20%20%7D%7B2%7D%2C%5Cfrac%7B1-5%20%20%7D%7B2%7D%5CRight%29)
M = ![(3,-2)](https://tex.z-dn.net/?f=%283%2C-2%29)
Now, Find the slope of the line :
It is perpendicular to the line with (4,1) and (2,-5)
Slope between (
) and (
) = ![\frac{y_{2}-y_{1} }{x_{2}-x_{1} }](https://tex.z-dn.net/?f=%5Cfrac%7By_%7B2%7D-y_%7B1%7D%20%20%7D%7Bx_%7B2%7D-x_%7B1%7D%20%20%7D)
so,
the slope between (4,1) and (2,-5) = ![\frac{-5-1 }{2-4 }](https://tex.z-dn.net/?f=%5Cfrac%7B-5-1%20%20%7D%7B2-4%20%7D)
= 3
perpendicular lines have slopes the multiply to get -1
3 times m=-1
m= ![\frac{-1}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B-1%7D%7B3%7D)
The equation of a line that has a slope of m and passes through the midpoints M(3,-2) is
![y-y_{1} =m(x-x_{1} )](https://tex.z-dn.net/?f=y-y_%7B1%7D%20%3Dm%28x-x_%7B1%7D%20%29)
![y-(-2) =\frac{-1}{3} (x-3 )](https://tex.z-dn.net/?f=y-%28-2%29%20%3D%5Cfrac%7B-1%7D%7B3%7D%20%28x-3%20%29)
![(y+2) =\frac{-1}{3} (x-3 )](https://tex.z-dn.net/?f=%28y%2B2%29%20%3D%5Cfrac%7B-1%7D%7B3%7D%20%28x-3%20%29)
if we want slope intercept form
![(y+2) =\frac{-1}{3} x+1](https://tex.z-dn.net/?f=%28y%2B2%29%20%3D%5Cfrac%7B-1%7D%7B3%7D%20x%2B1)
![y= \frac{-1}{3} x-1](https://tex.z-dn.net/?f=y%3D%20%5Cfrac%7B-1%7D%7B3%7D%20x-1)
If we want standard form
![\frac{1}{3} x+y = -1](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B3%7D%20x%2By%20%3D%20-1)
![x+3y =-3](https://tex.z-dn.net/?f=x%2B3y%20%3D-3)
Hence, Equation of a line is
