Graphs of two or more straight lines can be used to solve simultaneous linear equations. The graph of a straight line can be described using an equation close equationA mathematical statement ...

This paper is mainly concerned with the realizability of a set of n integers as the degrees of vertices of an n-vertex linear graph. Other related problems, such as when a set of integers is ...

Indicator functions are constructed under the linear-quadratic parameterization for contrasts, and applied to the study of partial aliasing properties for three-level fractional factorial designs. An ...
