Either way, the process is the same. Let's assume you meant:
Step 1: Pick a value, any value, for x. Since it doesn't matter what value you select, I would pick something divisible by 3 since that will make the arithmetic easier. So let's go ahead and use 3 for the first one.
Step 2: Substitute your selected value in place of x and then do the arithmetic required to determine the resulting value of y.
So, when x = 3, y = 2.
Step 3: Form the ordered pair (x,y): (3, 2).
Repeat this process three more times with three different values for x.
