How to Find Points on a Coordinate Grid

You must have remembered that in algebra a coordinate system or a coordinate grid is a 2-dimensional plane where there are two lines going from the center. The vertical line is called the y-axis and the horizontal line is called the x-axis. Both these axes have a negative value and a positive value. These values divide the entire coordinate system into four quadrants. While in the center there is origin with coordinates (0, 0). Finding point on a coordinate grid is not exceedingly difficult. It is exactly like finding two intersecting points based on their x and y values. The first number corresponds to the x-coordinates and the second to the y-coordinate. The completeness property for points in the plane tells us two things: Exactly one point in the plane is named given the numbers of the ordered pair and exactly one ordered pair of numbers names a given point in the plane. To graph a point, one draws a dot at the coordinates that corresponds to the ordered pair. It's always a good idea to start at the origin. The x-coordinate tells you have many steps you have to take to the right (positive) or left (negative). And the y-coordinate tells you have many steps to move up (positive) or down (negative).
