Question 19
<h3>Answer: No, it is not in quadrant 3.</h3>
Explanation:
In order to be in quadrant 3, we need two things
- x must be negative
- y must be negative
An example point in the third quadrant is (-9, -12).
Both (x,y) coordinates must be negative to be located in quadrant 3. This is the southwest quadrant on the xy grid. We're told that x = 0 which means we are not in quadrant 3. Points on the x or y axis are not part of any quadrant. They are on the boundaries between quadrants (think of it like a fence or a wall).

Question 20
<h3>Answer: No, it is not in quadrant 2</h3>
Explanation:
We use a very similar idea as the previous question. Since y = 0, this point is on a boundary and not in any quadrant. To be in the second quadrant, we need these two conditions to be true:
- x must be negative
- y must be positive
For example, the point (-5, 7) is in quadrant 2. This quadrant is in the northwest on the xy grid.
