Does the relation in the table represent direct variation, inverse variation, or neither? If it is direct or inverse variation, write an equation to represent the relation. Explain your answer.

x; 5,10,15,20
y; 2,1 ,2/3,1/2

Can someone please help me with this? I really don't understand what to do.

  1. if xy is constant, it's inverse. xy=k
    If y/x is constant, it's direct. y=kx

    So, take a look and see what you find.

  2. inverse ... y gets smaller as x gets bigger

    x y = 10
