Is the relationship between the variables in the table a direct variation, an inverse variation, both, or neither? if it is a direct or inverse variation, write a function to model it.

x 2 5 15 20
y 20 15 2 2

a. inverse variation;y=10/x
b. neither
c. direct variation; y=x+10
d. direct variation; y=10x

  1. If xy is constant, it's inverse
    If x/y is constant, it's direct

    Looks like (b) to me

    (c) is a bogus answer in any case.
