    Answer:

    (4, 2.5 )

    Step-by-step explanation:

    Given endpoints (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is

    ( \frac{x_{1}+x_{2}  }{2}, \frac{y_{1}+y_{2}  }{2} )

    Here (x₁, y₁ ) = (- 1, 2) and (x₂, y₂ ) = (9, 5) , then

    midpoint = ( \frac{-1+9}{2}, \frac{2+5}{2} ) = ( \frac{8}{2}, \frac{7}{2} ) = (4, 3.5 )
