ECZ 2013 · O-Level Paper 1 — Vectors In Two Dimensions
Given that vector AB = 1-3 and B is the point (4, 5), find the coordinates of A.
- A. (5, 2)
- B. (3, 2)
- C. (5, 8)
- D. (3, 8)
Verified working — step 1
AB = B - A, so rearrange: A = B - AB - subtract the vector from B, component by component.The full step-by-step working and final answer are included with Premium — checked against ECZ marking standards.
