Answer
See graphs, $(4,2)$
Work Step by Step
1. See graphs
2. Use $y=\sqrt {x}$ in $y=6-x$ to get $\sqrt x=6-x$ or $x+\sqrt x-6=0$
3. Factor to get $(\sqrt x+3)(\sqrt x-2)=0$, thus $\sqrt x=2$ (discard the negative answer) and $x=4$
4. Use the 2nd equation again to get $y=2$
5. We can find the intersect(s) $(4,2)$
