Show transcript
Graphs can be described by looking at how quickly they fall.
The amount y decreases when x increases by one is the rate of change and is called the gradient.
The gradient will be negative if y decreases as the graph moves to the right.
The gradient can be found from any linear graph.
The gradient tells us important information about the relationship.
