In this tutorial I show you how to draw displacement time graphs and how gradient gives velocity.

to get gradient for a to b… I always say change in y/change in x. doing so gives me 0.5 not -0.5 what am I doing wrong because this is how I’ve always been calculating gradient

Please show us your working and we may be able to help.
