Explicação passo a passo:
[tex]\mathsf{M = \{\dfrac{x_A + x_B}{2};\dfrac{y_A + y_B}{2}\}}[/tex]
[tex]\mathsf{M = \{\dfrac{2 + (- 2)}{2};\dfrac{-2 +(- 6)}{2}\}}[/tex]
[tex]\mathsf{M = \{\dfrac{2 - 2}{2};\dfrac{-2 - 6}{2}\}}[/tex]
[tex]\mathsf{M = \{\dfrac{0}{2};\dfrac{-8}{2}\}}[/tex]
[tex]\boxed{\boxed{\mathsf{M = \{0;-4\}}}}\leftarrow\textsf{letra C}[/tex]
