y=4x


y=−7x

x=9y

y=x8

xy=12

Answer 1

The equations that represent inverse variation are:

1) y=4x
2) y=−7x
3) x=9y
4) xy=12

So, all of the given equations represent inverse variation.

Answer 2

x y = 12
is
y = 12 / x
which is an inverse relationship.

Answer 3

Apologies for the mistake. Yes, you are correct. The equation "xy=12" represents inverse variation because it can be written as "y = 12/x". Thank you for pointing that out.
