Please see the graph.

$3x-y \leq 4$ Let's pick a point to see if the point is on the side of the line to shade. We can choose $(1,0)$. $3x-y \leq 4$ $3*1-0 \leq 4$ $3-0 \leq 4$ $3 \leq 4$ $3\leq 4 $ is true, so we shade the side of the line with the point. Since we have a less than or equal sign, we use a solid line.
