Systems of Linear Equations

Graphs the two lines associated with a system of two linear equations in two variables, showing the solution of the system as the point where the lines intersect (if a unique solution exists).

How to use
The text input fields can accept any decimal number input.

The buttons under the graph allow various manipulations of the graph coordinates.


Examples
Independent:   
x+2y=8
3x-2y=0
Dependent:   
2x-y=0
-4x+2y=0
Inconsistent:   
2x-y=0
2x-y=2

Other Notes
The labels under the text input field tell whether the system is independent, dependent, or inconsistent, and in the independent case also give the coordinates of the solution point (where the two lines cross). This information is determined as follows:
