Coordinates

An ordered pair (x, y) locates a point on a coordinate grid. Move from the origin along the x-axis first, then parallel to the y-axis. Positive and negative signs show direction.

Your goals

  • ✓You can plot and read points on a coordinate grid.
  • ✓You can use coordinate, origin correctly.
  • ✓You can move along the x-axis first, then the y-axis.

Words to know

coordinate:
An ordered pair, written (x, y), that locates a point.
origin:
The point (0, 0), where the axes meet.

Examples

  • 1For (3, 2), move 3 units right and 2 units up from (0, 0).
  • 2For (−4, 1), move 4 units left and 1 unit up from (0, 0).

Check these

  • • Do not swap the x-coordinate and y-coordinate.
  • • Keep every number, symbol, label, and unit in its correct place.
  • • Show enough working to check how you reached your answer.

Helpful habits

  • • Read the whole question before choosing what to do.
  • • Show one clear step at a time and check each step.
  • • If you are stuck, draw a model, try smaller numbers, or revisit the example.

Now try your own

Create your own coordinates example, solve it, and explain how you checked it.
