Study the marking See what earns credit and compare it with a full-mark answer.
Marking points
- 1 At least three known points are within half a small square of their correct coordinates.
- 2 All five known points are within half a small square of their correct coordinates.
Why this answer loses marks
I joined the rows into a line without plotting coordinates.
Each known pair needs its own point at the correct horizontal and vertical position.
