Answer: C

Step-by-step explanation:

plug in y=8 to

x+y=3

x+8=3

x=-5

There is no need to look at the other answer choices since they do not have x equaling to -5.

So,

[tex]x+y=3\Rightarrow y=3-x[/tex]

Then,

[tex]8=3-x\Rightarrow x=-5[/tex]

The ordered pair is therefore,

[tex]C(-5,8)[/tex]

Hope this helps.
