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 ...

In graphing linear equations by using a t-chart, all we have to do is plug in random values for x and random values for y and get our points that way. So using a t-chart, we are going to draw a chart ...

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 ...

Linear equations can be shown on a graph. Find out how to create one in this Bitesize KS3 maths video.
