Answer:
[tex]\text{Segment midpoint formula}[/tex]
Step-by-step explanation:
[tex](\frac{x1 + x2}{2},\frac{y1+y2}{2})[/tex]
For example:
[tex]\text{Points: } (4,9) (8,4)[/tex]
As long as you appropriately place the X and Y points, it doesn’t matter which [tex]x \underset{1}[/tex] etc you use.
[tex](\frac{4+8}{2},\frac{9+4}{2}) = 6, 6.5[/tex]
[tex]\text{X midpoint: 6}\\\text{Y midpoint: 6.5}[/tex]
