Support (from Y7 teaching programme) • Express simple functions in words • Generate coordinate pairs that satisfy a simple linear rule; recognise straight-line graphs parallel to the x -axis or y -axis.
Core (from Y8 teaching programme) • Express simple functions in symbols; represent mappings expressed algebraically. • Generate points in all four quadrants & plot the graphs of linear functions where y is given explicitly in terms of x, on paper; recognise that equations of the form y = mx+c correspond to straight-line graphs . • Discuss and interpret graphs arising from real situations. • Construct linear functions arising from real-life problems and plot their corresponding graphs • Solve more demanding problems and investigate in a range of contexts: algebra • Solve more complex problems by breaking them into smaller steps or tasks, choosing and using efficient techniques for algebraic manipulation
Extension (from Y9 teaching programme) • Find the inverse of a linear function • Plot graphs of linear functions ( y given implicitly in terms of x ), e.g. ay + bx = 0, y + bx + c = 0, on paper and using ICT; given values for m and c , find the gradient of lines given by equations of the form y = mx + c . • Discuss and interpret distance–time graphs
