interpret and use graphs in practical situations, including travel graphs, time series and conversion graphs
3.3.5
draw graphs from given data to represent practical situations
3.3.6
describe trend as increasing or decreasing for time series data
3.3.7
identify the rate of change of the dependent variable, relating it to the difference pattern in a table and the slope of an associated line drawn from practical contexts
3.3.8
determine and describe the significance of the vertical intercept in practical situations
3.3.9
use the rate of change and the initial value to determine the linear relationship in practical situations
3.3.10
interpret the point of intersection and other important features of given graphs of two linear functions drawn from practical contexts; for example, the ‘break-even’ point
