ECZ 2019 · GCE Paper 1 — Coordinate Geometry
The equation of line A is 3x + 2y = 10. Line B is parallel to line A and passes through the point (4, 6). Find the equation of the line B.
- A. y = −³⁄₂x + 12
- B. y = ³⁄₂x + 12
- C. y = −³⁄₂x + 5
- D. y = −²⁄₃x + 12
Verified working — step 1
Parallel lines share a gradient but not a constant - read the gradient off line A, then use the given point for the new c.The full step-by-step working and final answer are included with Premium — checked against ECZ marking standards.
