Which table shows a proportional relationship between x and y?

The second table

Step-by-step explanation:

For the table to show  proportional relationship between x and y , then they must have a common ratio. that is x/y must be the same throughout

Table 1

= 1                 = 2

= 3               = 5

= 4               = 8

= 7               = 14

= 1/2

= 3/5

= 4/8 = 1/2

= 7/14 = 1/2

Since the ratio is not the same throughout , then x and y are not proportional

Table 2

= 7               = 1

= 14               = 2

= 28               = 4

= 35               = 5

= 7/1 = 7

= 14/2 = 7

= 28/4 = 7

= 35/5 = 7

Since the ratio is the same throughout , it means that x and y are proportional.

Doing the same for table 3 and 4 , x and y are not proportional
