First graph the line,
y=-2x-1
+graph%28+300%2C+300%2C+-5%2C+5%2C+-5%2C+5%2C+-2x-1%29+
The line divides the plane into two regions.
Now choose a convenient point to check the inequality.
The point cannot lie on the line.
The origin is easist, in this case (0,0).
If the point satisfies the inequality, it's in the valid region.
If if doesn't, it's not in the valid region.
Plug it into your inequality.
0%3E-2%280%29-1
0%3E-1
The inequality is true so (0,0) is in the valid region.
Shade the region containing (0,0).
