Question

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

Answer 1

help pleassssssssssse

Answer 2

As x increases, y increases. But I am not so sure about the values... Are you sure the first y point is 6 and not 9 ?

Answer 3

yes thats what it says. it's a multiple choice answer, here are my choices;
yes; y = 2x
yes; y = 3x
yes; y = 4x
no; y does not vary directly with x

Answer 4

Well if that's the case you have to conclude that y does not vary directly with x.

If the first y value was a '9' instead of a '6', then y = 3x would have worked. But since that is not the case . . . there is no direct relation :(

Answer 5

okay, thank you so so much! :)
