Graphical representations of linear equations

In this unti we develop understanding of linear relationships and explore the key features of a linear equation such as the gradient, intercept and determining an equation from coordinate pairs.

Prior knowledge

Rearrange equations into y = mx + c form
Use tables of values to plot lines
Identify features of straight-line graphs

Source curriculum references

Use standard units of mass, length, time, money and other measures, including with decimal quantities
Model situations or procedures by translating them into algebraic expressions or formulae and by using graphs
Recognise, sketch and produce graphs of linear and quadratic functions of 1 variable with appropriate scaling, using equations in x and y and the Cartesian plane
Reduce a given linear equation in 2 variables to the standard form y = mx + c; calculate and interpret gradients and intercepts of graphs of such linear equations numerically, graphically and algebraically
Use linear and quadratic graphs to estimate values of y for given values of x and vice versa and to find approximate solutions of simultaneous linear equations
Relate the language of ratios and the associated calculations to the arithmetic of fractions and to linear functions
