Coordinate Geometry

🔹 What Is It?

Coordinate geometry uses grids to locate points using ordered pairs (x, y).

🧩 Clue to Remember

Always go across first, then up:
(x, y) = (horizontal, vertical)

🔹 Example

Point (3, 2) means
move 3 units to the right, then 2 units up on the graph.

💡 Why It Matters

Used in maps, games, charts, coding, GPS, and engineering.
