Course description
We'll first learn coordinate notation to place points in the coordinate plane. We'll then move on to describing lines and regions with equality and inequality expressions, before moving on to finding the distance between points in the plane.
Topics covered
- Plotting points.
- Negative coordinates.
- Vertical and horizontal lines.
- Regions described by inequalities.
- Gridline distance.
- Direct distance.
- Pythagoras' Theorem.
