You know that, right?

It is a graph in which the intersection of two straight lines (one horizontal and one vertical) is the origin (0,0).

A vector points from here to there on the axis, so it is called a vector.

Don't go too far when you are dizzy.

A coordinate axis includes all points on the axis.

Who stipulates that it is only on the straight line of two paintings?

Generally, the vector we define will be somewhere on the axis.

Axis contains the coordinates of all points, which is collective, not two lines. ..
