What are the coordinates of the midpoint of ab?

Answer:
(A)(6,-3)
Step-by-step explanation:
The coordinates of A and B are (4,-5) and (8,-1) respectively.
Let P is the mid point pf AB, then using the mid point formula, we have
[tex]P=(\frac{x_{1}+x_{2}}{2},\frac{y_{1}+y_{2}}{2})[/tex]
[tex]P=(\frac{4+8}{2},\frac{-5-1}{2})[/tex]
[tex]P=(\frac{12}{2},\frac{-6}{2})[/tex]
[tex]P=(6,-3)[/tex]
Thus, option A is correct.
