Answer

NO is the answer.

The table does not represent a proportional relationship.

Step-by-step explanation

When two quantities x and y are said to be proportional to each other, this is represented by

y ∝ x

Introducing the constant of variation, k, we have

y ∝ x

y = kx

We can then solve for k knowing that for two proportinal quantities, the value of k will remain the same for corresponding values of x and y

x | y

0 | 2

2 | 4

4 | 6

y = kx

when x = 0, y = 2

y = kx

2 = (k) (0)

2 ≠ 0

This first shows that the two quantities aren't proportional

when x = 2, y = 4

y = kx

4 = (k) (2)

2k = 4

k = 2

when x = 4, y = 6

y = kx

6 = (k) (4)

4k = 6

k = (3/2)

The values of k aren't consistent through the values in the table, hence, we cvan see that this data in the table does not represent proportional relationship.

Hope this Helps!!!
