$(6,7)$

Explanation:

$f(6)$ means that $x=6$
and
$f(6)=9$

Okay, let's make this equation now then

$f(x)=g(x)+2$

You know that the original $f$ equation takes place at $6$ , so you might as well use this since you have the most information about this point
$f(6)=g(6)+2$

Now just substitute what you already know ( $f(6)=9$ )
$9=g(6)+2$

Then solve
$g(6)=7$

so at $x=6$ , $g=7$
so the coordinate is $(6,7)$
