Answer 1

xy=k is a hint

Answer 2

C?!

Answer 3

wait no they want y

Answer 4

@mrbarry please come back

Answer 5

Inverse variation of x and y implies x * y = a constant
What is x * y according to the problem?

Answer 6

-21

Answer 7

and -21 is constant so that means that we can do -21/3 which is -3

Answer 8

thanks!!!
