Solve each system of inequalities by graphing:
2x+y<(less than or equal to) 4
y+1>(greater than or equal to) -2x
--------------------------------------------
ALWAYS graph the boudary of the inequality first:
Graph y = -2x+4 with a solid line because = is included in your equation.
Then shade the area BELOW the boundary because you want y LESS than -2x+4
------------------------
Graph y = -2x-1 with a solid line.
Then shade the half-plane ABOVE the boundary because you want y GREATER
than -2x-1
------------------------
The solution set is the intersection of the two graphs.
