The horizontal line is called the horizontal axis
It is the x axis.
a coordinate system
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.
X-axis
The horizontal line is called the horizontal axis
It is the x axis.
the x coordinate is whatever number on the horizontal line of your graph that you choose
"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
a coordinate system
The horizontal line in the Cartesian plane is called the x-axis or x-coordinate.
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.
X-axis
No, in the Cartesian coordinate system it would show a vertical line whose intersection of the x-axis is 4.
In the co-ordinate plane The horizontal number line is the 'x-axis'. The vertical number line is the y-axis. They intersect at the 'origin' ; coordinate (0,0) In the 3-dimensional system there is a third number line going from front to back , this is the z-axis. All three axes intersect at the origin , and have the the coordinates ( x,y,z) = (0,0,0)
Horizontal axis.
To find out the coordinates of a point in the coordinate system you do the opposite. Begin at the point and follow a vertical line either up or down to the x-axis. There is your x-coordinate. And then do the same but following a horizontal line to find the y-coordinate.
