Find the midpoint of the segment with the given endpoints. ​(9​,9​) and ​(-1​,- 3​)
GenaCL600 [577]

Answer: (4, 3)

Step-by-step explanation:

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

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

x_{1} = 9

x_{2} = -1

y_{1} = 9

y_{2} = -3

Substituting the values into the formula , we have :

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

Mid-point = ( \frac{8}{2} , \frac{6}{2} )

Mid - point = ( 4 , 3)
