Question 103638
1.  Solve the equation for y (if necessary).

{{{3x+y <= 1}}}  => {{{3x-1 <= y}}}  or {{{y >= 3x-1}}}


2.  Graph the equation as if it contained an = sign.
3.  Draw the line solid if the inequality is   or  
4.  Draw the line dashed if the inequality is < or > 
5.  Pick a point not on the line to use as a test point.
     The point (0,0) is a good test point if it is not on
     the line.
6.  If the point makes the inequality true, shade that
     side of the line.  If the point does not make the
     inequality true, shade the opposite side of the line.


now you can graf it and shade everything to the right from the line.
