Edexcel IGCSE Math A syllabusMath A 4MA1First assessment 2018

Practise region-description questions by identifying each boundary line and deciding which side of the line contains the shaded region.

How this is tested

  • Write three inequalities that define a shaded region bounded by straight lines.
  • Use solid or boundary-line information to decide whether ≤, ≥, is needed.

Question 10(b)

[Maximum number: 3]

The region R, shown shaded in the diagram, is bounded by three straight lines.
