PLS HELP!!!!

Answer 1

Second table

The reason why this table doesn’t look proportional is due to the fact that it has a missing part. There should be an extra box of x:21 and y:3, making this graph proportional throughout.

Answer 2

Answer:

Second table

Step-by-step explanation:

Proportional relationships between x and y satisfied the following equation y = k*x, where k is some constant. Rearranging we get: k = y/x. So, if we take every pair y-x and divided them, we have to find the same k.

- Division y/x for the first table:

2/1 = 2

5/3

8/4 = 2

14/7 = 2       It is not a proportional relationship

- Division y/x for the second table:

1/7

2/14 = 1/7

4/28 = 1/7

5/35 = 1/7       It is a proportional relationship

- Division y/x for the third table:

4/1 = 4

10/2 = 5

12/3 = 4

16/4 = 4        It is not a proportional relationship

- Division y/x for the fourth table:

5/2.5 = 2

6/3 = 2

10/5 = 2

15/6 = 5/2        It is not a proportional relationship
