🛎️ The Coordinate System
- The x-axis is horizontal and the y-axis is vertical.
- The point where they meet is called the origin (0,0).
🛎️ How to Locate a Point on a Grid
- A point is written as (x, y).
- Move along x first, then up or down y.
🛎️ Reflecting Points over y-axis
- Change the sign of the x-coordinate.
- The y-coordinate stays the same.
🛎️ Reflecting Points over x-axis
- Change the sign of the y-coordinate.
- The x-coordinate stays the same.
🛎️ Reflecting in the Origin
- Change the sign of both x and y.
- The point moves to the opposite quadrant.
🛎️ Reflecting Shapes
- Reflect every vertex using the same rule.
- Then connect the reflected points to form the new shape.
