    Correct answer is A. 9

    Step-by-step explanation:

    If y varies inversely with x the formula reads y = k/x

    where the k is coefficient of proportionality

    Now we will replace x=3 and y=6 to find value of k

    6 = k / 3 = > k = 6 · 3 = 18 = > k = 18

    Now we will replace x=2 and get y

    y = 18/2 = 9 = > y=9

    God with you!
