Construct and interpret graphs in real-world contexts.
e.g. distance-time, money conversion, temperature conversion
see also Direct proportion, 5.02a, Inverse proporion, 5.02b
Recognise and interpret graphs that illustrate direct and inverse proportion./i
Understand the relationship between gradient and ratio.
Interpret straight line gradients as rates of change.
e.g. Gradient of a distance-time graph as a velocity.
**Calculate or estimate gradients of graphs, and interpret in contexts such as distance-time graphs, velocity-time graphs and financial graphs.
Apply the concepts of average and instantaneous rate of change (gradients of chords or tangents) in numerical, algebraic and graphical contexts.**
Calculate or estimate areas under graphs, and interpret in contexts such as distance-time graphs, velocity-time graphs and financial graphs.
