I am totally stuck on this question, can some one help?
Come up with and describe two scenarios: one that models a direct variation situation and one that models an inverse variation situation. Do not state explicitly which scenario is which, but provide at least four data pairs for each situation. Your classmates will have to determine which of the scenarios is a direct variation and which is an inverse variation, and the value of k for each.

Direct:
y = kx
As x increases, y increases
distance = rate(time)
y/x = k
miles/time = rate
100, 5
200, 10
400, 20
800, 40
Inverse xy = k
As x increases, y decreases
As pressure increases on a gas, the volume decreases.

800 1/4
