Find y when x = 3, if y = -4 when x = -9

The value of y when x =3 is -12

Let the variable y be inversely proportional to x such that y = k/x

If y = -4 when x = -9, the value of k will be given as:

k = -9*-4

k = 36

To find the value of y when x = -3, we will use th relationship;

y = k/x

y = 36/-3

y = -12

Hence the value of y when x =3 is -12
