2x-3y>_9 and -x-4y>_8

both should be solid, because the solution is greater than OR equal to the line.

which way should the shading be though?

solve for y in each equation, and it answers your question.

2x-3y>=9

y<=-3+2x/3 so the area BELOW y (y is less than or equal to the line..)

check my math

and

y<=-1/4 x -8 again, it says y is on or below the line...(less than or equal)

what.?
