ECZ 2017 · GCE Paper 1 — Coordinate Geometry
The diagram shows a Cartesian plane with points A(6, 6), B(0, −2), C(0, 6) and D(6, 0). Find the equation of the line CD.

- A. y = x + 6
- B. y = −x − 6
- C. y = x − 6
- D. y = −x + 6
Verified working — step 1
C sits ON the y-axis, so the intercept is free - only the gradient needs working out.The full step-by-step working and final answer are included with Premium — checked against ECZ marking standards.
