#1**+1 **

what i do is look to see if point 0,0 is included.

as in subsitute 0 for x and y

0 is <= 10 so 0,0 is shaded for that one

0 is not < -1, so 0,0 is not shaded for that one.

< implies a dotted line, where <= implise a solid line.

The lower right is the only one that fits all this.

You could also put each equation in y=mx+b and draw the lines.

Then plug in 0,0 to see which direction to shade.
