Answer:

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!!!
