Answer:

-162

Step-by-step explanation:

y = k / x

Plug in values.

18 = k / -9

Solve for k by multiplying both sides by -9.

k = -162

The value of k is -162.

We have given that the point P(x,y)=(-9,18)

That is x=-9 and y=18

Graph of the function is,

y = k / x

What will we get after the plunging the value of x and y in given function?

[tex]18 = k / -9[/tex]

Solve for k by multiplying both sides by -9.

[tex]18*-9=k[/tex]

k = -162

Therefore we get the value of k is -162.
