## xbob 2 years ago need help with test pls

1. xbob

1. For the data in the table, does y vary directly with x? If it does, write an equation for the direct variation. yes; y = 2.75xyes; y = 0.6875xyes; y = 1.375xno; y does not vary directly with x

3. xbob

i cant fail it again

We can not see the table as it is.

Take a printscreen of the question.

15. FriedRice

so this is a review right?

16. xbob

yes thats what i said i just cant fail

17. FriedRice

no; y does not vary directly with x As you can see.....y=2x, y=4x and y=8x are not true from the table.

18. FriedRice

wait no!!!

19. xbob

can you help me for a bit or are you busy

20. FriedRice

to vary directly means to increase as it increases as x gets bigger, y gets bigger; so there is some direct variance at play if the ratio between x and y is the same for each point; then you will know the constant of variation looks to be a ration of 8/11 = x/y y = (11/8)x 1.3 ... id go the 3rd option

21. xbob

it took you that long to write wait no

22. FriedRice
