Marking points
- 1 Determines Δx as 0.042 m from the marked graph interval.
Full-mark answer
Δx = 0.052 m − 0.010 m = 0.042 m.
Why this answer loses marks
I used the vertical side of the gradient triangle.
This part asks for the horizontal change, so both endpoints must come from the horizontal axis.
