Suppose that x and y vary inversely and that x = 2 when y = 8. Write the function that models the inverse variation. A. y = 16/x

B. y = 10/x

C. y = 4x

D. y = 6/x

The correct answer to this question is this one: A. y = 16/x

x and y varies inversely.

so meaning

x = k / y

when y=8, x=2

2 = k / 8

so this will give us the value of k

k = 16

x = k/y

xy = k

y = k/x

y = 16 / x

A. y = 16/x
