Check my work?

If y varies inversely with x and y = 6 when x = 3, then what is y when x = 2?



9
12
18 ♥
36

Answer 1

"y varies inversely with x" means that y = k/x for some constant k

plug in y = 6, x = 3

y = k/x

6 = k/3

6*3 = k

18 = k

k = 18

So the equation is y = 18/x

Now plug in x = 2

y = 18/x

y = 18/2

y = 9

Answer 2

Ohh so i was somewhat wrong. thank you :]
