LO-1Construct a straight-line graph using a linear function of the form, 𝑦 = 𝑚𝑥 + 𝑐 where 𝑚 is slope (gradient) and 𝑐 is 𝑦-intercept.LO-2Construct and analyse a straight-line graph to model a given linear relationship, e.g. modelling the cost of filling a fuel tank of a car against the number of litres of petrol required.LO-3Determine the slope (gradient), 𝑥-intercept and 𝑦-intercept of a straight line from both its equation and its graph.LO-4Interpret, in context, the slope (gradient) and intercept of a linear function used to model and analyse a practical situation.LO-5Understand and use the slope-intercept form of a linear function, 𝑦 = 𝑚𝑥 + 𝑐 where 𝑚 is slope (gradient) and 𝑐 is 𝑦-intercept.
