To find coordinates, just do the x point, y point.
So:
1. (3, 5)
2. (4, 3)
3. (4, 0)
4. (0, 4)
5. (-5, 0)
6. (-4, 3)
7. (-2, 2)
8. (-4, -2)
9. (-2, -3)
10. (3, -2)
The x-axis is the horizontal bolded line and the y-axis is the vertical bolded line, so therefore:
11. Point S and Point K
12. Point R and Point Z
And if you need an explanation on how to do 13 or 14, I guess you could just tell me because I'm too lazy to write it out:
13. 3
14. (1, -3), and (0, -3)
And the y-coordinate value is just the second number, or where it is on the vertical line.
15. Point N and Point T
