Cartesian coordinates

You’re given a list of points on the plane. Determine which quadrant each point is in. If the point is located on an axis, write $X$ or $Y$ for the axis it's on. If it is located at the origin, write $0$.

1. $(1,2)$
2. $(-5,0)$
3. $(-7,-2)$
4. $(0,0)$
5. $(-1,16)$
6. $(0,8)$
7. $(3,4)$
8. $(8,-2)$

Write your answers in order without spaces, for example: “2x40y3xy”.
