Direct and inverse proportion

By the end you’ll be able to

• Solve direct and inverse proportion problems using unitary and multiplier methods (e.g. recipes, workers and time)
• Form and use equations of the form $y = kx^n$ and $y = \frac{k}{x^n}$, including square, cube and square-root relationships (Higher)
• Recognise and sketch graphs of direct and inverse proportion, and read the constant of proportionality from them
