Hi
2x + y < 4   OR y < -2x + 4
I.  Graph line y = -2x + 4 by plotting points a couple of points(0,4) and (1,2)
for ex and connect with a 'dotted line' due to the < sign. (cannot demonstate that here)
{{{drawing(300,300, -6, 6, -6, 6, grid(1),
circle(0, 4,0.3),
circle(1, 2,0.3),
graph( 300, 300, -6, 6, -6, 6,0,-2x+4))}}}
II.  Shade below the dotted line to show the graph of the Inequality 
*[invoke plot_any_inequality "y< -2x + 4", -10, 10, -8, 12, 300, 300]
