Question 76912
The given set of equations are: 


{{{y = x/3 + 1/2}}} 

{{{y = x/3 - 2 }}}


The graph of both the equations ae as follows:


{{{graph( 300, 200, -10, 10, -10, 10, x/3 + 1/2, x/3 - 2)}}} 



Here we observe that both the equations are parallel to each other and hence the given set has no solutions.


I hope the steps are clear. You can get back to me if you have any queries.
