Study Plan

1
Day 1–2

Learn the Theory

Read the textbook chapter carefully. Note down definitions, formulas and key ideas. Focus on: 1. Cartesian Coordinate System and Quadrants, 2. Distance Formula, 3. Section Formula and Midpoint.

2
Day 3

Practise

Solve the textbook exercises and extra practice questions. There are 49 questions available for this chapter.

3
Day 4

Revise & Test

Revise key points without looking at your notes. Take a practice quiz and mark weak areas for another pass.

4
Day 7

Spaced Revision

Come back to Cartesian System of Coordinates after a week. Use flashcards for quick recall and try past exam questions on this chapter.

What to Focus On

  • The origin is the point (0, 0).
  • The x-coordinate is called the abscissa; the y-coordinate is called the ordinate.
  • The plane is divided into four quadrants based on the signs of x and y.
  • Quadrant I: x > 0, y > 0
  • Quadrant II: x < 0, y > 0
  • Quadrant III: x < 0, y < 0
  • Distance is always non-negative.
  • The formula is symmetric: distance from P to Q is same as from Q to P.
  • Distance from origin to point (x, y) is √(x² + y²).

Common Mistakes to Avoid

The distance between two points is just the difference in x-coordinates or y-coordinates.

The order of points doesn't matter in the section formula.

Area of triangle can be negative, so we ignore the sign.

Memory Tips

Quadrant Sign Rules: I (+,+), II (−,+), III (−,−), IV (+,−)

Distance Formula: √[(x₂−x₁)² + (y₂−y₁)²]

Section Formula (Internal Division): ( (m₁x₂ + m₂x₁)/(m₁+m₂) , (m₁y₂ + m₂y₁)/(m₁+m₂) )

Midpoint Formula: ((x₁+x₂)/2, (y₁+y₂)/2)
