If y varies inversely as x, find the constant of variation if y = 2 as x = -9.

Constant of variation (k) = -18

Step-by-step explanation:

We are given that y varies inversely as x and we are to find the constant of variation (lets assume its if and .

∝

Changing this inverse proportionality to equality to get:

Substituting the given values:

k = -18

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y

x=y+6

therefore your answer is

x =y+6

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4
