Answer:
D
Step-by-step explanation:
Given endpoints (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is
( [tex]\frac{x_{1}+x_{2} }{2}[/tex] , [tex]\frac{y_{1}+y_{2} }{2}[/tex] )
Here (x₁, y₁ ) = J(3, - 6) and (x₂, y₂ ) = K(4, - 7) , then
midpoint = ( [tex]\frac{3+4}{2}[/tex] , [tex]\frac{-6-7}{2}[/tex] ) = ( [tex]\frac{7}{2}[/tex] , [tex]\frac{-13}{2}[/tex] ) = (3.5, - 6.5 )
