Sub Topic Name : Plotting A Point In The Plane If Its Coordinates Are Given |
What is a Cartesian plane?
Basic knowledge about coordinates and Cartesian system
Every place on the map can be uniquely specified by a pair of numbers or a coordinate.

World map | Name a place and ask the student to indicate the coordinates of the place using the latitude as the X-axis and longitude as the Y-axis |
Maps, global positioning systems, navigation systems, travel compass, target systems

Maps GPS | The maps use latitudes and longitudes as the coordinates to give the location of a place. The GPS system also uses latitudes and longitudes as the coordinates to give the location of the place. They also use the height factor to give the height of place from mean sea level. |
Cartesian system is used in coordinate geometry to locate points. A Cartesian plane is divided into four parts by the axes. The center is called the origin. The value of coordinates differs in each part.
To define the location of a place on a world map, we need to mark the distance of the place from the Y-axis called the X-coordinate and the distance of the place from X-axis called the Y-coordinate. Here X-coordinate is the longitude and Y-coordinate is the latitude.
