You can put this solution on YOUR website! Can you graph the inequality.
y≥1-3x
------------
You have to graph the boundary: y=1-3x
Plot two points:
(If x=0, y=1; If x=1,y=-2)
Plot those points and draw a line thru them.
That takes care of the EQUALITY.
--------
To graph the INEQUALITY pick a test point like (0,0)
Substitute those values into the inequality:
0>1-3*0
0>1
That is wrong so that side of the boundary is NOT the solution
set of the INEQUALITY; tho other side is so darken the other side.
--------
The line and the darkened side (half-plane) is the graph you want.
