One powerful way to do this is through a routine called slow reveal graphs.

It is also possible to have a conversion graph to switch between units that are not directly proportional. For example, temperature can be measured in degrees Centigrade (°C) and degrees Fahrenheit ...

If an equation can be rearranged into the form \(y = mx + c\), then its graph will be a straight line. In the above: \(x + y = 3\) can be rearranged as \(y = 3 - x\) (which can be re-written as \(y = ...
