Exercises 9–14, determine the quadrant(s)
in which (x, y) could be located.
9. x > 0 and y < 0
I say this is quadrant 4.
10. x < 0 and y < 0
I say this is quadrant 3.
11. x = −4 and y > 0
I say this is quadrant 2.
12. x < 0 and y = 7
I say this is quadrant 2.
13. x + y = 0, x ≠ 0, y ≠ 0
Not sure about 13.
14. xy > 0
I say this is quadrant 1.
You say?
