Question 1206305

{{{ x-3y<0}}}...first solve for {{{y}}}

{{{ x<3y}}}

{{{3y>x}}}

{{{y>(1/3)x}}}

graph it as any equation of a line, just your line is not part of the solution and should be dashed line
solution will be shaded area above the line 

 {{{ graph( 600, 600, -10, 10, -10, 10, y>(1/3)x) }}}

here is better graph:
