What you need to know
Check yourself against these “I can” statements.
- I can solve simultaneous equations using graphs
- I can show inequalities as regions on a graph and interpret them
- I can find approximate solutions to quadratic equations from a graph
- I can rearrange an equation so I can solve it using a graph I already have

4 resourcesSolving Quadratics and Cubics Graphically
The graph of y = f(x), a quadratic or a cubic (choose, or mix), is drawn: read approximate solutions of f(x) = 0, then f(x) = a and f(x) = g(x) by drawing a line, then equations that must be rearranged to find the line to draw.…
🔤 Fill the GapsFill the Gaps: Maths Vocabulary
A sentence explaining one of the unit’s key words, with gaps. Pick the right word for each gap from the words scattered round it: the right ones and plenty of wrong ones. A deck for every unit.
🧮 ToolGraph Plotter
A graphing calculator: type y = f(x), x = g(y), implicit relations such as x² + y² = 25, inequalities (shaded, dashed for < and solid for ≤), parametric and polar curves, points and tables, functions f(x) = … with f′(x), and…
