Answer:
[tex] \boxed{ \bold{ \huge{ \boxed{ \sf{(4 \: , \: 0)}}}}}[/tex]
Step-by-step explanation:
Let the points be A and B
Let A ( 9 , 6 ) be ( x₁ , y₁ ) and B ( -1 , -6 ) be ( x₂ , y₂)
Finding the mid points of the line segment joining these points
[tex] \boxed{ \sf{midpoint = ( \frac{x1 + x2}{2} , \: \frac{y1 + y2}{2} )}}[/tex]
[tex] \longrightarrow{ \sf{( \frac{9 + ( - 1)}{2} , \: \frac{6 + ( - 6)}{2}) }}[/tex]
[tex] \longrightarrow{ \sf{ (\frac{9 - 1}{2} \: , \: \frac{6 - 6}{2} }})[/tex]
[tex] \longrightarrow{ \sf{( \frac{8}{2} , \: \frac{0}{2} }})[/tex]
[tex] \longrightarrow{ \sf{(4 \: , \: 0}})[/tex]
Hope I helped!
Best regards! :D
