Answer:

y = 16

Step-by-step explanation:

Use the inverse variation equation, y = \frac{k}{x}

Plug in 8 as x and 4 as y, then solve for k

y = \frac{k}{x}

4 = \frac{k}{8}

32 = k

So, k is 32.

The equation is y = \frac{32}{x}

Plug in 2 as x and solve for y

y = \frac{32}{x}

y = \frac{32}{2}

y = 16

So, when x = 2, y = 16
