Q: What does IP Maths Notes (Lower Sec, Year 1-2): 04) Coordinate Geometry & Graphs cover?
A: Understand gradients, intercepts, distance and midpoint formulas, and sketch linear graphs with contextual interpretations.
Coordinate geometry links algebra to visuals. This note refreshes gradient logic, distance and midpoint formulas, equation forms, and graph interpretation.
These notes align with MOE Lower Secondary Mathematics syllabus used in IP pathways (aligned to O-Level Mathematics 4048 foundations).
Status: MOE Lower Secondary Mathematics syllabus (latest release) checked 2025-11-30 - scope unchanged; remains the reference for these lower-sec notes.
Learning targets
- Compute gradients and intercepts from points or equations.
- Convert between point-slope, slope-intercept, and general linear forms.
- Apply the distance and midpoint formulas accurately.
- Interpret real-world scenarios from line graphs (rate, supply-demand, temperature).
1. Gradient and intercepts
- Gradient (slope) between points
