Question

30. For the data in the table, does y vary directly with x? If it does, write an equation for the direct variation.
x y
3 6
6 18
8 24 (1 point)
yes; y = 2x
yes; y = 3x
yes; y = 4x
no; y does not vary directly with x

Answer 1

the first answer y = 2x only works with x = 3 and y = 6, no with the others
then y = 3x, does not work with x = 3 and y = 6
y = 4x does not work with any

Answer 2

So, no Y does not vary directly with x? @ivettef365
