In analytic geometry, the number axis in the horizontal direction is called the horizontal axis or the X axis, and the number axis in the vertical direction is called the vertical axis or the Y axis.

In the plane rectangular coordinate system, any point can be represented by a pair of ordered numbers. The reading method of number pairs is to read the horizontal axis coordinates first, and then read the vertical axis coordinates after a pause.

Such as (2, 3), that is, read 2 first, then read 3.

But in specific cases, when exploring how to describe the location of objects or graphics in mathematical language, for example, the location of schools on the map is the third group and the second group.

The location of the school on the map is (3,2).

The position of the school is horizontal axis 3 and vertical axis 2, which is pronounced as three commas and two.

Generally, we use ordered number pairs in analytic geometry, so we just need to pause and finish reading it.
