Easy Examples of Ordered Pairs in Coordinate Math

📚 Quick Study Guide

• 📍 Ordered Pair Definition: An ordered pair is a pair of numbers written in a specific order, usually in parentheses, such as $(x, y)$. The order matters! $(2,3)$ is different from $(3,2)$.
• 🧭 Coordinate Plane: Also known as the Cartesian plane, it's formed by two perpendicular number lines: the x-axis (horizontal) and the y-axis (vertical).
• 📈 Plotting Points: To plot a point $(x, y)$, start at the origin $(0, 0)$. Move $x$ units horizontally (right if positive, left if negative) and then $y$ units vertically (up if positive, down if negative).
• ➕ Quadrants: The coordinate plane is divided into four quadrants:
  • Quadrant I: x > 0, y > 0
  • Quadrant II: x < 0, y > 0
  • Quadrant III: x < 0, y < 0
  • Quadrant IV: x > 0, y < 0
• ➗ Origin: The point (0, 0) where the x-axis and y-axis intersect.
