Given parameters:
The coordinates are:
P1 (8, -4) and P2 (-3, 9)
Unknown:
The midpoint of the endpoints = ?
Solution:
x₁ = 8
y₁ = -4
x₂ = -3
y₂ = 9
midpoints; x[tex]_{m}[/tex] , y[tex]_{m}[/tex] = [tex]\frac{x_{1} + x_{2} }{2} ,[/tex] [tex]\frac{y_{1} + y_{2} }{2}[/tex]
= [tex]\frac{8 +(-3)}{2}[/tex] , [tex]\frac{-4 + 9}{2}[/tex]
= [tex]\frac{5}{2}[/tex] , [tex]\frac{5}{2}[/tex]
The coordinate of the x-axis is [tex]\frac{5}{2}[/tex]
