No, sorry, I agree with irs1054. 'Displacement' can go down, 'distance' is cumulative and so can never go down on a graph like this. Using distance to mean displacement is incorrect and is likely to confuse students.

Unlike IRS1054 I do like this, all the way through. Distance time graphs can go down - the distance is the distance from the starting point, not the distance travelled, so if you walk away from home then turn round and come back you are back where you started!
Many thanks for sharing - I'm going to use this with my year 9 maths set tomorrow.

Useful for first slide with equation and layout of graph. Pity about the final graph though. Distance-time graphs can never go down. Once you have started on a journey the distance you travel either increases or stays the same it can never decrease.
