Rectangular coordinate system

In mathematics,Previously we have discussed about column addition worksheets and In today's session we are going to discuss about Rectangular coordinate system which comes under andhra pradesh education, Graph can be considered as an important tool that provides the visual representation of the data. Basically graphs are used for representing the relation between two or more variables like x and y variables. In mathematics, normally two dimensional graphs are used for representing relationship between two or more variables. In the concept of graph, rectangular coordinate system is popularly known as Cartesian coordinate system or x-y coordinate system. According to rectangular coordinate system definition, it is a system in which coordinate point having a distance form a set of perpendicular lines. A rectangular coordinate system consist four quadrants, dual perpendicular lines that is a horizontal line and a vertical lines and they also has the origin point.
In graph horizontal lines are called as x – axis and vertical lines of the graph are called as y axis of the graph. When the both x – axis and y axis of the graph crosses each other than that point are known as origin point. In mathematics, rectangular coordinate system is used for representing all the values which are generated by the graphical equations. To represent the value of an equation we need to create a table of values which are generated by the graphical equations.
Rectangular coordinate system is split into four quadrants. In this system all the values are associated with the ordered pair. In ordered pair x coordinate considered as first value and y coordinate considered as second value. In rectangular coordinate system, the 1st quadrant contains the positive value of x and y axis. In the same aspect 2nd quad contains the negative x and positive y. In the same aspect the quad 3rd and 4th is working as inverse of quad 1st and quad 2nd.
Example: Plot the given ordered pairs on the graph?
                           X (2, 3), Y (-2, - 3)
Solution: In the 1st ordered pair both value of x axis and y axis contains the positive value that why this pair plotted on the 1st quad. In the same aspect 2nd ordered pair contains the both negative value of x and y axis then this pair lies in 3rd quad.
In the next session we will discuss about Sketching and modeling and You can visit our website for getting information about algebra tutor.
