Answer:
Step-by-step explanation:
x: 2 5 8
y: 2 0.8 0.5
Simply by looking at what happens to y as x increases, we can see that y decreases, and that we therefore have inverse variation.
The appropriate model is y = k/x.
If x = 5, y = 0.8, and so 0.8 = k/5
Solving for the constant of proportionality, we get 4 = k.
Then y = 4/x models this data.
