I am not into your dashed or solid lines, but here is the way to solve.

y>= -3x+10

draw that line (thru the points 0,10 and 3.33,0
so the inequality includes the line, and all points in areas below the line, including the origin
is it b
i looked the equation up on desmos
actually it would be all the points above and including the line y = -3x+10
