Answer:
(- [tex]\frac{9}{2}[/tex], [tex]\frac{1}{2}[/tex] )
Step-by-step explanation:
Using the midpoint formula
Given 2 points (x₁, y₁ ) and (x₂, y₂ ), then midpoint is
([tex]\frac{x_{1}+x_{2} }{2}[/tex], [tex]\frac{y_{1}+y_{2} }{2}[/tex])
with (x₁, y₁ ) = (- 1, 5) and (x₂, y₂ ) = (- 8, - 4), then midpoint
= ([tex]\frac{-1-8}{2}[/tex], [tex]\frac{5-4}{2}[/tex] )
= ( - [tex]\frac{9}{2}[/tex], [tex]\frac{1}{2}[/tex] )
