In the system of Cartesian coordinates in geometry, the x-coordinate is the location in the horizontal direction (nominally left and right) while the y-coordinate is in the vertical direction (up and down). The line along which x values are measured is the x-axis.
An x-coordinate to the left of center (zero) is negative, and to the right is positive.
(In three dimensions, the x and y form a horizontal plane and the z coordinate is measured along the vertical axis.)

What is the definition to x-coordinate?
Given an ordered pair, (x,y), the first number is the x coordinate.
What is the definition of the X axis on the coordinate grid?
The bootom of the coordinate grid
When a point lies on the x-axis what do you know about it y-coordinatewhen a point lies on the y-axis what do you know about its x-coordinate?
If a point lies on the x-axis then by definition it is located at (x,0) ie the y coordinate is 0.If a point lies on the y-axis then it's located at (0,y) ie the x coordinate is 0.
What is the x coordinate called?
the "x" coordinate is called "x"
When a point lies on the x axis what do you know about its x coordinate?
you should know exactly what it is 2nd Answer: You nothing about its x coordinate, but the y coordinate = 0
