Answer: ( -6 , -6.5 )
Step-by-step explanation:
The formula for calculating Mid - point is given by
M = ([tex]\frac{x_{1}+x_{2}}{2}[/tex] , [tex]\frac{y_{1}+y_{2}}{2}[/tex] )
[tex]x_{1}[/tex] = -5
[tex]x_{2}[/tex] = -7
[tex]y_{1}[/tex] = -9
[tex]y_{2}[/tex] = -4
substituting into the formula , we have
M = [tex]\frac{-5-7}{2}[/tex] , [tex]\frac{-9-4}{2}[/tex]
M = [tex]\frac{-12}{2}[/tex] , [tex]\frac{-13}{2}[/tex]
Therefore : mid point = ( -6 , -6.5 )
