    Answer:

    Since

    y

    is inversely proportional to

    x

    , we can wite

    y

    =

    k

    x

    ,

    where

    k

    is a constant.

    Since

    y

    =

    2

    when

    x

    =

    8

    ,

    2

    =

    k

    8

    ⇒

    k

    =

    16

    Now, we know the complete formula

    y

    =

    16

    x

    .

    If

    x

    =

    12

    , then

    y

    =

    16

    12

    =

    4

    3

    .

    I hope that this was helpful.
