You can put this solution on YOUR website! graph the solution set of x+2y<3.
------------
1st: solve for "y":
y < (-1/2)x + (3/2)
-----------------------
2nd: Graph the boundary line y = (-1/2)x + (3/2)
----------------
3rd Since your problem calls for "y Less than" ,
shade the halfplane BELOW the line.
That halfplane is the graph of the inequality.
