Answer 1

@KamiBug @rebeccaxhawaii

Answer 2

look for a table where each value of y can be found by multiplying the x value by the same number.

Answer 3

the second one

Answer 4

if we look at table 1 :-

x = 1 y = 5
1*5 = 5
x = 3 y = 12
3*4 = 12

so this is not a proportional relation because we are multiplying x by different numbers

Answer 5

I don't get it none of them do that

Answer 6

okay it's easy @fluttershyK

Answer 7

like to learn the shortcut

Answer 8

Yes one does
Check out table 2

Another way to check would be to calculate y/x and see if its the same for every row

Table 2 y/x = 3/1 = 3
6/2 = what?

Answer 9

are you with me

Answer 10

then check out 12/4
and 15/5
