Answer: (4, 3)

Step-by-step explanation:

The formula for coordinate of the mid point is given as :

Mid point = ([tex]\frac{x_{2}+x_{1}}{2}[/tex] , [tex]\frac{y_{2}+y_{1}}{2}[/tex] )

[tex]x_{1}[/tex] = 9

[tex]x_{2}[/tex] = -1

[tex]y_{1}[/tex] = 9

[tex]y_{2}[/tex] = -3

Substituting the values into the formula , we have :

Mid-point = ([tex]\frac{-1+9}{2}[/tex] , [tex]\frac{-3+9}{2}[/tex] )

Mid-point = ( [tex]\frac{8}{2}[/tex] , [tex]\frac{6}{2}[/tex] )

Mid - point = ( 4 , 3)
