The coordinate table is like a window, each of which is called X and Y. Each of them, like the axis of numbers, has numbers containing zero and positive and negative numbers. The lines at the ends of these lengths are perpendicular to the coordinate axes, cut off at each other. This is the point of intersection of the geometric display of a given point. We can also guess this by specifying that we can understand the relations of numbers.
The upper number in the bracket represents the number on the horizontal axis, x-axis or longitudinal axis.
The lower number in the bracket shows the number on the vertical axis, the y axis or the transverse axis.
To find the coordinates of a point, we must start counting from the beginning of the axis or origin of the coordinate axis, which is a zero point.
