X-axis and Y-axis
Points on the coordinate plane are written with points from both the x-axis and the y-axis.
The x-axis runs horizontally (<-->) and moves from negative values on the left to positive values on the right.
The y-axis runs vertically (up and down) and move from negative values at the bottom to positive values at the top.
When points are labeled using the coordinate plane, they are written with the x-value first, followed by a comma and then the y-value. These values are enclosed with parentheses.
Example: (x , y)
(-2 , 4) reads as -2 on the x-axis and positive 4 on the y-axis. The point would be where -2 on the x-axis and positive 4 on the y-axis intersect.

Quadrants

The coordinate plane is broken down into quadrants, as shown on the left.
Quadrant 1 has positive x-values and positive y-values. (x , y)
Quadrant 2 has negative x-values and positive y-values. (-x , y)
Quadrant 3 has negative x-values and negative y-values. (-x , -y)
Quadrant 4 has positive x-values and negative y-values. (x , -y)
The very center point of the coordinate plane lies at the point (0 , 0) which is known as the origin.
