5. The >= condition indicates you will need a solid line, because

3x+y = 10

is part of the solution. So, B and D are the only possibilities.

Now draw that line. Since you want

3x+y >= 10

you shade the part of the plane above the line, as that's where the sum of 3x+y is more than 10.

So, since (0,0) is below the line (0+0 < 10) you want to shade the part away from the origin: (B)
