The final table is in the attached picture.
Before beginning, you should note that:
To get rid of a fraction, this fraction should be multiplied that is equal to or is a multiple of its denominator.
This means that:

Now, for the given:
We have the equation:

The denominator of the fraction is 3, therefore to get rid of it we will need x to be a 3 or a multiple of 3.
Let's consider the x values to be -3, 0, 3 and 6.
For x = -3:
= -3 + 2 = -1 .....>First order pair is (-3,-1)
For x = 0:
= 0 + 2 = 2 .....> Second order pair is (0,2)
For x = 3:
= 1 + 2 = 3 .....> Third order pair is (3,3)
For x = 6:
= 2 + 2 = 4 .....> Fourth order pair is (6,4)
Hope this helps :)
