First of all rewrite the equation in terms of x
3x – y = 1

===> Y = 3x -1


3x – y = 2

==> y = 3x -2

Now give arbitrary values to x in both equations and find out corresponding values of y.


Using these values plot the graph.


The the graph comes like this,

+graph%28+700%2C+700%2C+-10%2C+15%2C+-10%2C+10%2C+3x-1%2C+3x-2%29+




Since resulting lines are parellel, these two equations have no solution.
