In this video, i will be answering problem two from section 1, chapter 1, pre -calculus with limits.
00:08
In the question, it says, the point of intersection of the x and y axis is the blank, and the two axis divide the coordinate plane into four parts called blank.
00:20
So in the picture, i have sketched out my coordinate plane.
00:24
I'm going to begin by labeling my x -axis as the horizontal number line, and i'm going to label my y -axis, the vertical number line.
00:36
And the point of intersection of these two axes is the center right here marked with the red dot.
00:44
This intersection is called the origin.
00:47
It's called the origin because any time we are plotting a point, we begin at the origin and go left or right, depending on the first coordinate, and then up or down depending on the second coordinate.
01:02
Because this is the center, the coordinate for the origin is zero -zero.
01:09
Now, we also observe that the coordinate plane has been cut into four sections.
01:16
And because they're four sections, these sections are called quadrants.
01:20
The word quadrants coming from the latin of four.
01:24
Quadrants.
01:26
And the way that we label the quadrants as we start, in the upper right corner and we move counterclockwise...
