Getting ordered pair is easy as pie. You assign a value to, say, x, then you solve for the y.

Example,

x -2y = 6

Say, x=0, so,

0 -2y = 6

y = 6/(-2) = -3

Hence, the ordered pair here is (0,-3).

You need 3 ordered pairs for this equation. You need two more.

say, x=2, then,

2 -2y = 6

-2y = 6 -2 = 4

y = 4/(-2) = -2

Hence, (2,-2) is another ordered pair.

Last one, say x=4,

4 -2y = 6

-2y = 6 -4 = 2

y = 2/(-2) = -1

Hence, (4,-1), your 3rd ordered pair.

I am still a little confused. in the last problem where did you get the -4
