Answer:
[tex]\large\boxed{M\left(\dfrac{-1}{-2}\right)=\dfrac{1}{12}}[/tex]
Step-by-step explanation:
[tex]M=\dfrac{1}{6}\\\\\dfrac{-1}{-2}=\dfrac{1}{2}\qquad\qquad\bigg(\dfrac{negative}{negative}\to positive\bigg)\\\\M\left(\dfrac{-1}{-2}\right)=\dfrac{1}{6}\left(\dfrac{1}{2}\right)=\dfrac{(1)(1)}{(6)(2)}=\dfrac{1}{12}[/tex]
