**Coordinates**

**Coordinates** are a pair of numbers which are used to determine the position of a point or a shape in a 2-dimensional plane.

We define the position of a point on a 2D plane using two numbers, called the x-coordinate and the y-coordinate.

**Coordinates** are written as ordered pairs of numbersor using letters and numbers.

The **first** coordinate refers to the** x- axes** and the **second** coordinate refers to the **y- axes**:

** (x; y)** or **A (x; y)****Example: (-2, 3) or A(-2, 3)**

**Coordinate plane**

##### The coordinate plane is divided into **four sections**, called quadrants.

Quadrants are named **I, II, III** and **IV**, numbered in an **anti-clockwise direction**.

The** x- axes is horizontal** and the **y- axes is vertical**

**Quadrant I** has positive x and y values**Quadrant II** has negative x and positive y**Quadrant III** has negative x and y**Quadrant IV** has positive x and negative y

**Coordinate**

The **first coordinate** is called the **abscissa**, is the horizontal position according to the **x-axes**.

The **second coordinate** is called the **ordinate**, is the vertical position according to the **y-axes.**

The **coordinates used** on **coordinate planes, grids or maps**
