Straight-line graphs are tested at every tier and form the basis for understanding gradients, intercepts and real-world modelling. Students need to plot lines from equations, find gradients and interpret y = mx + c.
Our tutors see these errors again and again. Knowing them in advance gives you a head start.
Confusing gradient (steepness) with y-intercept (where the line crosses the y-axis)
Miscalculating the gradient by getting rise and run the wrong way round
Plotting points inaccurately on the coordinate grid
This topic is tested by the following exam boards. Our tutors are specialists in each one.
Simultaneous equations require students to find values that satisfy two equations at the same time. Foundation students solve linear pairs, while higher-tier students tackle one linear and one quadratic equation together.
AlgebraInequalities extend equation-solving skills by introducing ranges of solutions rather than single values. Students must solve, represent on number lines, and at higher tier shade regions on graphs defined by multiple inequalities.
AlgebraQuadratic graphs produce a characteristic U-shape (parabola) and are tested at both foundation and higher tier. Students must plot quadratics from tables, identify key features like turning points and roots, and use graphs to solve equations.
