Question 1177547
graph {{{2y-4x<8 }}}

do it as you do with {{{2y-4x=8 }}}

make table

{{{x}}}|{{{y}}}
{{{0}}}|{{{4}}}->{{{2y-4*0=8 }}}->{{{2y=8 }}}->{{{y=4 }}}
{{{-2}}}|{{{0}}}->{{{2*0-4x=8 }}}->{{{-4x=8 }}}->{{{x=-2 }}}

plot points and draw dashed line since you have {{{2y-4x<8 }}}

{{{drawing( 600, 600, -10, 10, -10, 10,
circle(0,4,.17),circle(-2,0,.17),
 graph( 600, 600, -10, 10, -10, 10, y<2x + 4)) }}}
