2 answers:
Answer:
y = 16
Step-by-step explanation:
Use the inverse variation equation, y = 
Plug in 8 as x and 4 as y, then solve for k
y = 
4 = 
32 = k
So, k is 32.
The equation is y = 
Plug in 2 as x and solve for y
y = 
y = 
y = 16
So, when x = 2, y = 16
Answer:
I'm pretty sure that it is 8 but I'm not entirely sure
