there is quadrant 1 , quadrant 2 , quadrant 3 , and quadrant 4
Quadrant
Its y-coordinate is zero.
Two axis. The x (horizontal) axis, and the y (vertical) axis.
"The" vertical line is wrong; there are lots of vertical lines on a coordinate plane. In the usual x-y coordinate system, such a line has an equation of the form:x = a (for some constant "a"); for example: x = 3

quadrants
Quadrant
Those are the four "quadrants".
I'm thinking quadrants would be the answer.
The x and y axis cross at (0,0) on the coordinate plane.
y-axis
It is the x axis
A coordinate plane consists of the y axis up and left and the x axis right and down
The horizontal number line on a coordinate plane is called the x-axis, and the vertical number line on a coordinate plane is called the y-axis.
Coordinate Plane
The vertical axis in a plane coordinate graph
I believe you mean the x-axis, the horizontal axis on a coordinate plane
