Correct Answer: North-EastYour Answer: D
Explanation
Step 1: Place the starting point at (0,0) and translate every move into x-y change. | Step 2: After cancellation, final coordinates are (9,5). | Step 3: The signs of (9,5) place the final point in the North-East direction. | Answer: Option D — North-East.
Important Notes
- Draw a north arrow before solving and take East as positive x, West as negative x, North as positive y, and South as negative y. |
- Combine opposite movements before calculating distance: cancel East with West and North with South. |
- Decide the final direction from the signs of the remaining horizontal and vertical displacements. For example, positive x and negative y indicate South-East. |
