Week 2 — Coordinate System & Straight Lines
- Cartesian/rectangular coordinate system
- Coordinates
- Slope
- Parallel lines
- Perpendicular lines
- Representations of a line
- General equation of a line
- Straight-line fitting
Core patterns:
Line representations:
and
Recognition patterns:
- Two points → find line.
- Point + slope → find line.
- Two lines → determine parallel/perpendicular.
- Equation → extract slope/intercept.
- Data points → straight-line fit.
Harder questions will combine geometry + algebra + interpretation.
