11. Quadrant II
12. Between Quadrant II and III
13. Quadrant I
14. Quadrant IV
15. Quadrant III
This is simple. Since you already plotted the points you just have to see which box the point is in. The top right box is Quadrant I. The top left box is Quadrant II. The bottom left box is Quadrant III. And finally, the bottom right box is Quadrant IV. Also, if the point ever lands on the x- or y- axis, just say it is between Quadrant _ and Quadrant _.
Hope this helps! :)
