Mathematics — first biennium · Lesson
An ordered pair is always read as (x,y): horizontal displacement first, then vertical displacement.
In this lesson: Read and write coordinates (x,y) and identify quadrants.
How to proceed: Start at the origin: read x on the horizontal axis first, then y on the vertical axis. The signs of the two coordinates determine the quadrant.
You can already assume: Integers: sign, order and number line.

Start at the origin: read x on the horizontal axis first, then y on the vertical axis. The signs of the two coordinates determine the quadrant.
Given data: Point P is marked on the graph.
ConceptStep separates what is required from what is recommended or useful as reinforcement. Only required prerequisites block your progress.
Relationships: solid line = required · dashed line = recommended · dotted line = reinforcement.
