What you need to know
Check yourself against these “I can” statements.
- I can plot straight-line graphs, including ones like ax + by = c
- I can rearrange an equation into the form y = mx + c
- I can find the gradient and y-intercept from the equation of a line
- I can compare two lines using their equations

3 resourcesGradient Golf
Eighteen holes of mini golf on a grid where every shot is aimed with a gradient: count the squares from the ball to the hole, type the gradient (whole numbers, fractions, decimals, or undefined from the drop-down), then choose…
🧮 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…
🧩 ConnectionsStraight Lines
Match straight lines given as equations, gradient and intercept, two points or intercepts. Parallel lines and swapped gradient/intercept from Standard; perpendicular lines on Hard.
