A linear equation is represented as a line graph. In order to draw the line graph we require several pairs of coordinates. These coordinates represent the relationship given in the equation.

One way to assess this fluctuating data is to add a linear trend line to the Excel 2013 graph. This visual element considers all the data and displays the overall direction the values are taking.

Very few cost-variable relationships are perfectly linear. However, accountants can still apply the linearity assumption if the relationship between the cost and the variables that affect it are ...

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 ...
