Does the data in the table represent a direction variation or an inverse variation, write an equation

x 1 2 5 10
y 40 20 8 4

My answer is a direct variation, y=40x, is this correct?

here are the other answers

direct variation 7=1/40x
inverse variat xy=40
inverse xy=1/40

asked by abbey
  1. while 40 = 40*1, 20 ≠ 40*2
    so, your first guess is wrong.

    However, note that x*y=40 for all the items.
