The horizontal line is called the horizontal axis
On the Cartesian plane the horizontal number line is the x axis.
It is called the "ordinate" axis.
It is a parallel or a colinear line
It is simply a horizontal line. No special name, unless you're referring to the axis/axes. The horizontal line is the 'x-axis' in a graph.
It is called a horizontal line!
The horizontal line is called the horizontal axis
a horizontal line.
The horizontal row is called period.
On the Cartesian plane the horizontal number line is the x axis.
abscissa is horizontal and ordinate is vertical one
It is called the "ordinate" axis.
The coordinate plane is formed by the intersection of a vertical and a horizontal number line. What is the horizontal number line called?
On the Cartesian plane the horizontal number line is the x axis.
A line which divides a body into two parts, such that each part is the mirror image of the others, then the line is called a line of symmetry. If such a line is parallel to the horizontal plane, then it is called a horizontal line of symmetry. Else, if the line of symmetry is perpendicular to the horizontal plane then it is a vertical line of symmetry.
The vertical line is called the y-axis and the horizontal is called the x-axis.
It is a parallel or a colinear line
