Summary of Co-ordinate Geometry for ICSE Class 9 Mathematics. Key concepts, important points, and chapter overview.
Overview
Co-ordinate Geometry is a branch of mathematics that combines algebra and geometry to study the position of points and geometric figures using a coordinate system. It uses pairs of numbers called coordinates to represent the exact location of points on a plane with respect to two perpendicular numbe
Key Concepts
A system that uses pairs
A system that uses pairs of numbers (coordinates) to represent the position of points with respect to two mutually perpendicular number lines called c
In equations like y = 3x
In equations like y = 3x + 5, if y is expressed in terms of x, then y is the dependent variable (its value depends on x) and x is the independent vari
A pair of numbers written
A pair of numbers written in specific order as (a,b) where a is the first component and b is the second component. The order matters: (3,5) ≠ (5,3). T
The coordinate plane is divided into
The coordinate plane is divided into four quadrants by the x and y axes. First quadrant: (+,+), Second quadrant: (-,+), Third quadrant: (-,-), Fourth
To plot a point (a
To plot a point (a,b): start from origin, move 'a' units along x-axis (right if positive, left if negative), then move 'b' units parallel to y-axis (u
