Systems of linear equations form a fundamental part of linear algebra. Finding the slopes of graphs and graphing proportional relationships and equations. For example the function C 2 pi r is a linear function because only the C and r are real variables with the pi being a constant.
Now plot these points in the graph or X-Y plane.
