Introduction
To graph, or plot, points we use two perpendicular lines called the x axis and the y axes.
Horizontal number line is the x axis and the vertical line is the y axis. The part of x axis towards right of origin is the positive x axis and the one towards left of origin is the negative x axis. Similarly the part of y axis above the origin, is the positive y axis and the part of y axis below the origin, is the negative y axis. Every point in the coordinate plane is represented by an ordered pair of x and y coordinates.
Consider the example −
Using the pencil, plot the point −3,2
Solution
The first coordinates tell about the right/left movement from the origin
The second coordinate tells about the up/down movement from the origin.
Since x coordinate is a −3, there is a movement towards the left 3 units from the origin. The y coordinate is 2, which means movement two units vertically up to get to the point −3,2.
Rules to plot a point in the coordinate plane given its ordered pair
1.We move along the x axis that many units from the origin left/right as the x coordinates.
2.Then we move up/down vertically as many units as the y coordinate to locate the point in the coordinate plane.
