We use coordinates to describe the position of a 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.
Look at the points below. K has coordinates (1, 4). N has coordinates (-3, 1). F has coordinates (-3, -3) and P has coordinates (1, -3).
