 * __Locus __** One of the benefits of a graph is that it can show a geometric picture of algebraic equations and situations can then be analysed. The reverse can also happen. Geometric conditions can be written as algebraic equations. Locus is an attempt to describe either in algebraic or geometric terms the path of a point which moves so that it always obeys a given condition.
