## Coordinate Geometry Class 9 Maths all Formulas

- Cartesian coordinate system: A system which describe the position of a point in a plane is called Cartesian system.
- Cartesian coordinate axis: Let us draw a horizontal line XX’ and a vertical line YY’ in a plane. Both the lines intersect each other at 90°, then the plane is divided into four parts. The lines XX’ and YY’ are called axes i.e., XX’ is the x-axis and YY’ is y-axis.
**Quadrant**When XX’ and YY’ intersect each other then the plane is divided into four parts. These parts are called quadrants. The plane is known as Cartesian plane or XY plane.**Coordinate Geometry**: It is a branch of geometry in which geometric problems are solved through algebra by using coordinate system.- Cartesian Coordinate (Rectangular Coordinate) System In this system, the position of a point P is determined by knowing the distances from two perpendicular lines passing through the fixed point O is called origin. The position of the point P from origin on x-axis is called x-coordinate and the position of P from origin on y-axis is called y-coordinate.
**Abscissa**: The distance of a point P from y-axis is called abscissa.**Ordinate**: The distance of a point P from x-axis is called its ordinate.- In first quadrant values of x and y are both positive.
- In second quadrant value of x is negative whereas the value of y is positive.
- In third quadrant value of x and y both are negative.
- A point which lies on y-axis has the coordinates of the form (0, b).
- A point which lies on x-axis has the coordinates of the form (a, 0).
- In fourth quadrant, the value of x is positive and value ofy is negative.
- Perpendicular distance of a point from x-axis = (+)y-coordinate.
- Perpendicular distance of a point from y-axis = (+)x-coordinate.
