Take one of the points in the table,

like  x=1  y=5
or    x=2  y=7

Write them into one of the choices on the list,
and see if the result is true.

For example,

-- Take the line in table that says   x=1   y=5.

-- And take the first choice on the list     y = x + 3 .

-- Write '1' in place of 'x', and write '5' in place of 'y'.

-- Then you have    5 = 1 + 3 .

Is this true ?  I don't think so.
So the first choice on the list can't be correct.

Try thesame point    x=1   y=5   with  the other choices.
You'll find one that IS correct, and that's the answer.
