20. The y-coordinate is zero and the x-coordinate is negative. Is the point in Quadrant II?
Explain.

Question 19

Explanation:

In order to be in quadrant 3, we need two things

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

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:

For example, the point (-5, 7) is in quadrant 2. This quadrant is in the northwest on the xy grid.
