This problem wants us to list the quadrant or quadrants satisfying the following condition where y divided by x or y over x is less than zero.
00:08
And to be able to figure this out, let's first review where our quadrants are.
00:12
We have quadrant 1, where both our x value and our y value is positive.
00:18
And then we go in a counterclockwise rotation to number our quadrants.
00:21
So quadrant 2 is here.
00:23
And quadrant 2 has negative x value while still having a positive y value for any point in that quadrant.
00:30
Then we have the third quadrant, moving along, again, counterclockwise rotation.
00:34
In the third quadrant, we have negative x's and negative y.
00:38
And for our last quadrant, quadrant four, before we make the full revolution, that has positive x values, but negative y values.
00:46
So when we look at the condition that we're supposed to keep true for the quadrants that we select, we have y divided by x being shown to be less than zero.
00:59
If it's less than zero, what that's telling us is that y dividing by x is negative...
