Answer 4

Right, no I'm from England. We use different terminology is all. We call direct variation direct proportion. Or at least, I've never heard direct variation anyway. Direct variation is basically when all the x values are multiplied by the same number to get the y value. On table 4 you multiply the first value by 3, the second by 4 and the third by 5 so that isn't direct variation. On the third table, you add 3 each time so you can't be multiplying by the same value. On the second table you multiply the first x value by three and not the second or the third so that isn't either. However on the first table you multiply 6 by 1.3333 to get 8 and you multiply 9 by 1.3333 to get 12 and 12 by 1.33333 to get 16. So the first table is Direct Variation as you are multiplying each x value by 1 and a third.
