Overview

Coordinate Geometry is a branch of mathematics that helps us describe the exact position of any point on a plane using two perpendicular lines called axes. Just like we use latitude and longitude to locate places on Earth, we use the Cartesian coordinate system to locate points on a flat surface. Th

Key Concepts

The Cartesian coordinate system consists

The Cartesian coordinate system consists of two perpendicular number lines that intersect at a point called the origin. The horizontal line is called

The origin is the point where

The origin is the point where the x-axis and y-axis intersect. It is the reference point from which all distances are measured. The origin is always l

The x

The x-axis is the horizontal number line in the coordinate system. It runs from left to right. The x-coordinate (also called the abscissa) of any poin

The y

The y-axis is the vertical number line in the coordinate system. It runs from bottom to top. The y-coordinate (also called the ordinate) of any point

The coordinates of a point

The coordinates of a point are a pair of numbers written in the form (x, y) that precisely describe where the point is located on the coordinate plane

Learning Objectives

  • Understand the concept of the Cartesian coordinate system and its components
  • Learn to identify and plot points using x and y coordinates
  • Understand the role of axes, origin, and quadrants in locating points
  • Master the terminology of coordinates: abscissa (x-coordinate) and ordinate (y-coordinate)
  • Apply coordinate geometry concepts to real-world situations
