Checking my answers
For the data in the table, does y vary directly with x? If it does, write an equation for the direct variation.
X 3,6,8
Y 6,18,24
I got no; y does not vary directly with x

Answer 1

You are correct.
3 x 2 = 6
6 x 3 = 18
8 x 3 = 24
To go from 3 to 6, you multiply by 2, but to go from 6 to 18, and from 8 to 24, you multiply by 3, so it does not vary directly. It's not linear. You are correct.

Answer 2

Thanks
