Study Plan

1
Day 1–2

Learn the Theory

Read the textbook chapter carefully. Note down definitions, formulas and key ideas. Focus on: 1. Basic Ideas: Co-ordinates, Ordered Pairs, and Axes, 2. Quadrants and Sign Convention, 3. Points on the Axes.

2
Day 3

Practise

Solve the textbook exercises and extra practice questions. There are 37 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.

Day 7

Spaced Revision

Come back to Co-ordinate Geometry after a week. Use flashcards for quick recall and try past exam questions on this chapter.

What to Focus On

  • Variables x and y are used in linear equations.
  • The variable written as the subject is the dependent variable.
  • The other variable is the independent variable.
  • An ordered pair has two numbers in a fixed order.
  • The first number is the first component and the second is the second component.
  • Order matters in ordered pairs.
  • The cartesian plane has two perpendicular number lines.
  • The horizontal line is the x-axis.
  • The vertical line is the y-axis.

Common Mistakes to Avoid

The first number in an ordered pair can be swapped without changing the point.

A point on the x-axis has y as its first component, and a point on the y-axis has x as its second component.

The x-axis has slope undefined and the y-axis has slope 0.
