does the data in the table represent a direct variation or an inverse variation?
x 2 4 8 12
y 4 2 1 2/3
Choices:
inverse variation; xy = 8
direct variation; y = 8x
inverse variation;y/x = 8
*direct variation; y = 8/x
Thank You.

heck, just check each choice
Looks like xy=8 to me
inverse variation
y=8/x is correct, but it's an inverse variation 👍
