In 2-dimensions, it is the y-axis.
In 3-dimensions, though, the x and y axes form the horizontal plane and the z-axis is the vertical axis.
The horizontal line is the x axis and the vertical line is the y axis.
The z axis in the vertical axis in the Cartesian Coordinate System.
It is the vertical number line on the y axis in the Cartesian plane
The vertical y axis on the Cartesian plane is both negative and positive
The y-axis is the vertical line that is perpendicular to the horizontal line of the x-axis on the Cartesian plane
The vertical y axis on the Cartesian plane goes straight upwards
The horizontal line is the x axis and the vertical line is the y axis.
It is the vertical Y-axis on the Cartesian plane
The y axis on the Cartesian plane is a vertical number line
The z axis in the vertical axis in the Cartesian Coordinate System.
It is the vertical number line on the y axis in the Cartesian plane
The vertical y axis on the Cartesian plane is both negative and positive
The y-axis is the vertical line that is perpendicular to the horizontal line of the x-axis on the Cartesian plane
Cartesian plane
That's the name of the plane with the horizontal x-axis and the vertical y-axis on which equations and inequalities with two variables are graphed. The Cartesian coordinate plane is to two dimensions as the number line is to one dimension.
On the Cartesian plane the x line is the horizontal axis and the y line is the vertical axis.
They refer to the horizontal x axis and the vertical y axis that are perpendicular to each other on the Cartesian plane
