DETERMINING coordinate KARTISIUS

Previously, you have determined the coordinates of the location of objects and places. Now, you're learning how to determine the position of points on the Cartesian coordinate system. Come on, consider the following picture.



The picture is called Cartesian coordinates. Cartesian coordinate system consists of a horizontal axis (x-axis) and vertical axis (y-axis). The second axis function is to determine the position of a point. The points on a Cartesian coordinate point pairs on the x-axis and y-axis (x, y). Where X is called abscissa and y is called ordinate. Intersect
between the x-axis and y-axis at point 0 (zero) is called the center coordinates. Based on the Cartesian coordinate system that you can obtain the following information.


1. Point A is located at coordinates (1, 3).
2. Point B is located at coordinates (0, 4).
3. Point C is located at coordinates (-2, 1).
4. Point D is located at coordinates (4, -2).
5. Point E is located at coordinates (2, -4).

Are you able to determine location coordinates of points on the field? In order to determine location coordinates of points on the field, consider the following example.



Example 1
Find the location of point A on the field coordinates (2, 1), written A (2, 1).
Answer:

Move to the field coordinates two units from point 0 (zero) to the right. Then, move one unit upwards.


Example 2
Find the location of point B on the field coordinates (-3, -1), written B (-3, -1).
