For the data in the table, does y vary directly with x? If it does, write an equation for the direct variation. x|y 4|28 6| 48| 8| 72A. yes; y = 2x B. yes; y = 5xC. yes; y = 7xD. no; y does not vary directly with x

Let's have a look:

2(4)= 8 (this would not work)

5(4)= 20 (this wouldn't work)

7(4)= 28 This does, let's check the others.

7(6)= 42 This does not work.

"D" would be the correct answer.

I hope this helps!
