ECZ 2013 · O-Level Paper 1 — Coordinate Geometry
Find the equation of the line joining the point A(0, 7) to the point B(7, 0).
- A. y = x + 7
- B. x + y = 7
- C. y = x - 7
- D. x - y = 7
Verified working — step 1
Gradient = 0 - 77 - 0= -1, and the y-intercept is 7, so y = -x + 7, i.e. x + y = …The full step-by-step working and final answer are included with Premium — checked against ECZ marking standards.
