Answer:

y=3x ( the'=' sign is the proportionality sign)

Step-by-step explanation:

x = 1 , 2 , 3 , 4

y = 3 , 6 , 9 , 12

You are multiplying by 3 to get to y

1 x 3 = 3

2 x 3 = 6

3 x 3 = 9

4 x 3 = 12

well the table would look like this

     x      y

     1      3

     2      6

     3      9

     4      12

and the direct variation is y=3x but the constant of variation is k=3
