Step-by-step guide to finding the Midpoint
- The middle of a line segment is its midpoint.
- The Midpoint of two endpoints A \((x_{1},y_{1})\) and B \((x_{2},y_{2})\) can be found using this formula: M \(\color{blue}{(\frac{x_{1}+x_{2}}{2}, \frac{y_{1}+y_{2}}{2})}\)

Finding Midpoint – Example 1:
Find the midpoint of the line segment with the given endpoints. \((1, -2), (3, 6)\)
Solution:
Midpoint \(= (\frac{x_{1}+x_{2}}{2},\frac{y_{1}+y_{2}}{2}) → (x_{1},y_{1} )=(1,-2)\) and \((x_{2},y_{2} )=(3,6)\)
Midpoint \(=(\frac{1 + 3}{2},\frac{-2+6}{2}) → (\frac{4}{2},\frac{4}{2}) → M(2,2) \)
Finding Midpoint – Example 2:
Find the midpoint of the line segment with the given endpoints. \((-2, 5) , (8, -3)\)
Solution:
Midpoint \(=(\frac{x_{1}+x_{2}}{2},\frac{y_{1}+y_{2}}{2}) → (x_{1},y_{1 })=(-2,5)\) and \((x_{2},y_{2} )=(8,-3)\)
Midpoint \(=(\frac{-2 + 8}{2},\frac{5+(-3)}{2}) → (\frac{6}{2},\frac{2}{2}) → M(3,1)\)
Finding Midpoint – Example 3:
Find the midpoint of the line segment with the given endpoints. \((4,-5),(0,9)\)
Solution:
Midpoint \(=( \frac{x_{1}+x_{2}}{2},\frac{y_{1}+y_{2}}{2}) → (x_{1},y_{1} )=(4,-5)\) and \((x_{2},y_{2} )=(0,9)\)
Midpoint \(=(\frac{4 + 0}{2},\frac{-5+9}{2}) → (\frac{4}{2},\frac{4}{2}) → M(2,2) \)

Finding Midpoint – Example 4:
Find the midpoint of the line segment with the given endpoints. \((6,7),(4,-5)\)
Solution:
Midpoint \(=(\frac{x_{1}+x_{2}}{2},\frac{y_{1}+y_{2}}{2}) → (x_{1},y_{1} )=(6,7)\) and \((x_{2},y_{2} )=(4,-5)\)
Midpoint \(=(\frac{6 + 4}{2},\frac{7+(-5)}{2}) → (\frac{10}{2},\frac{2}{2}) → M (5,1)\)
