Plotting Coordinates in Four Moves

1

Start

Begin at the origin (0,0).

2

Move x

Move left or right along the x-axis.

3

Move y

Move up or down along the y-axis.

4

Plot

Mark and label the point accurately.

What You’ll Learn

Understand Coordinates

Read ordered pairs written as (x, y).

Use the Coordinate Grid

Identify the x-axis, y-axis and origin.

Plot Positive and Negative Points

Move accurately in all four directions.

Use Four Quadrants

Recognise the sign pattern in Quadrants I–IV.

Read Coordinates

Identify the coordinates of points already shown on a graph.

Key Rules

UnderstandingThe Coordinate Grid the Order

The horizontal axis is called the x-axis.
The vertical axis is called the y-axis.
The point where the axes meet is called the origin and has coordinates (0,0).

Worked Proof: Plotting Coordinates

Real-Life Applications

Coordinates are used in maps, GPS systems, computer graphics, engineering, architecture and data analysis.

More Worked Examples

1

Plot the coordinate (3,4).

Move 3 units right along the x-axis.

Move 4 units up the y-axis.
The point is located at (3,4).

2

Plot the coordinate (5,2).

Move 5 units right.

Move 2 units up.
The point is located at (5,2).

3

Plot (-2,5).

Move 2 units left.

Move 5 units up.
The point is located at (-2,5).

4

A point is 6 units right and 2 units up from the origin.

Answer: (6,2)
  • Common GCSE Mistakes
  • Order: Do not reverse the x and y values.
  • Counting: Count grid spaces carefully from the origin.
  • Negative directions: Left and down use negative coordinates.
  • Quadrants: Check the signs before naming a quadrant.
  • Graph scales: Read the scale on each axis before plotting.
  • Exam Tips
  • Remember x first: Move across before moving up or down.
  • Start from the origin: Use (0,0) as your reference point.
  • Check signs carefully: Negative x means left; negative y means down.
  • Learn the quadrant signs: (+,+), (-,+), (-,-), (+,-).
  • Label points clearly: Plot accurately and use the graph scale.

Frequently Asked Questions

Coordinates are an ordered pair of numbers that describe the position of a point on a graph.

Coordinates are written as (x, y), with x first and y second.

The origin is the point where the axes meet and has coordinates (0,0).

The x-axis is horizontal.

The y-axis is vertical.

Quadrant I (+,+), Quadrant II (-,+), Quadrant III (-,-), Quadrant IV (+,-).
