Verified Answer :

Second table, because:
if x=1, y=2
if x=2, y=4
...
if x=m, y=2m

:)

Answer:

In second table , x and y are proportional

Step-by-step explanation:

x and y are said to be proportional if y=kx where k is any real number .

For first table:

\(y eq kx\) for any real number k

So,  x and y are not proportional.

For second table:

\(3=1\times 3\\6=2\times 3\\12=4\times 3\\15=5\times 3\)

So, y=kx where k = 3

x and y are proportional.

For third table:

\(y eq kx\) for any real number k

So,  x and y are not proportional.

For fourth table:

\(y eq kx\) for any real number k

So,  x and y are not proportional.
