Answer:
D y = 9/x
Step-by-step explanation:
An inverse variation is of the form
xy = k where k is a constant
We can write this as
y = k/x
The only equation that is of this form is
D y = 9/x
Answer:
[tex]\boxed{\mathrm{Option \: D}}[/tex]
Step-by-step explanation:
Inverse variation is written as:
[tex]y=\frac{k}{x}[/tex]
Where k is the constant of proportionality.
