    y = 25

    Step-by-step explanation:

    y = k/x

    ; where

    x

    and

    y

    are variables and

    k

    is constant

    or

    5

    =

    k/10

    or

    k

    =

    5 (10)

    or

    k

    =

    50

    So Equation becomes

    y

    =

    50

    x

    When

    x

    =

    2

    y

    = 50/2

    or

    y

    =
