Fortunately, there is a simple way to make things appear a lot more organized without having to declutter your home, and it's called the straight-line technique. The trick is to organize ...

Draw the graph of \(y = 3x - 1\). If you recognise this as a straight line then just choose two ‘easy’ values of \(x\), work out the corresponding values of \(y\) and plot those points.

If you recognise this as a straight line then just choose two ‘easy’ values of \(x\), work out the corresponding values of \(y\) and plot those points. When \(x = 0\), \(y = 3 \times 0 - 1 ...

A simple tip suggests you install the first ... which makes following the straight line easier. A laser level, on the other hand, forms an optical beam in a straight line that guides the installation.
