Ch- 7 Coordinate Geometry

Basics of Coordinate Geometry

Points on a Cartesian Plane

Points on a plane are located by a pair of numbers called the coordinates.  The distance of a point from the y-axis is known as abscissa or x-coordinate. The distance of a point from the x-axis is called ordinates or y-coordinate.

Distance Formula

Distance between any two points (x1,y1) and (x2,y2) is given by

Where d is the distance between the points (x1,y1) and (x2,y2).


Section Formula:

he coordinates of the point which divides the line segment joining the points A(x1, y1) and B(x2, y2) internally in the ratio m : n are:
