ECZ 2025 · GCE Paper 1 — Coordinate Geometry

The points A and B are (−7, 1) and (−4, 5) respectively. Find the length of the line AB.

  • A. 5 units
  • B. 7 units
  • C. 25 units
  • D. 4 units

Verified working — step 1

The distance between two points comes from Pythagoras: the horizontal and vertical gaps are the short sides, AB is the hypotenuse.

The full step-by-step working and final answer are included with Premium — checked against ECZ marking standards.
