Question 948833
{{{(1/3)x - y >= 1}}}

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

or

{{{y<=(1/3)x -1 }}}

here is your line:

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

since you have <= sign, it would be a solid line meaning the boundary line {{{is}}} included in the solution and you need to shade below the line like this


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