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