ECZ 2011 · O-Level Paper 1 — Geometrical Transformations
A transformation is represented by the matrix 20-31. A point J is mapped onto the point Y(6, 16) by this matrix. Find the coordinates of J.
- A. (12, 34)
- B. (3, 7)
- C. (3, 25)
- D. (6, 16)
Verified working — step 1
Let J = (x, y). Then 2x = 6 gives x = 3, and -3x + y = 16 gives -9 + y = 16, so y = …The full step-by-step working and final answer are included with Premium — checked against ECZ marking standards.
