Graph the inequality on a coordinate plane.
\[5\le 3x+y or y \ge3x+5 ...(1)\] consider y=3x+5 when x=0,y=5 when y=0,x=-5/3 draw the line AB |dw:1384115820708:dw| put x=0,y=0 in (1) \[0+0 \ge 5\] which is not true. Hence origin does not lie on the graph. Line AB and the shaded region is the required graph.
