We use **coordinates** to describe the **position** of a specific point on a **coordinate grid**.

The coordinate grid is divided into four quadrants, shown below:

Coordinates are numbers written in brackets, like (3, 8) or (4, -2).

The first number is the **x-coordinate**.

This describes how far along the (horizontal) x-axis to go.

The second number is the **y-coordinate**.

This describes how far up the (vertical) y-axis to go.

**e.g. Look at the points shown on the coordinate grid below. **

**K has coordinates (1, 4). N has coordinates (-3, 1). F has coordinates (-3, -3) and P has coordinates (1, -3).**

Where both the x- and y-coordinates are **positive**, the coordinate will appear in the **1st Quadrant**.

Where the x-coordinate is **negative** but the y-coordinate is **positive**, the coordinate will appear in the** 2nd Quadrant**.

Where both the x- and y-coordinates are **negative**, the coordinate will appear in the **3rd Quadrant**.

Where the x-coordinate is **positive** but the y-coordinate is **negative**, the coordinate will appear in the **4th Quadrant**.

In this activity, we will identify the quadrant location of specific coordinates and solve problems involving coordinates using both negative and positive values for the x- and y-coordinates.
