Answer:
[tex](\frac{-9}{2},\frac{11}{2})[/tex]
Step-by-step explanation:
you have to use the midpoint formula which is
[tex](\frac{x1+x2}{2},\frac{y1+y2}{2})[/tex]
so you plug your numbers in
[tex](\frac{-12+3}{2},\frac{-3+-8}{2})[/tex]
Add the tops
[tex](\frac{-9}{2} ,\frac{-11}{2} )[/tex]
if possible simplify
and that is your answer
