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?

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

1. Steve

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

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

correct

3. Dani

the answer is C: inverse variation & xy=40
