Ugh I did this ages ago >.>

pick a point in the shaded... say (1, 1) and substitute it into each equation to test if its true or not... e.g. the last option is 1 <= -1 + 4 true... so that seems ok... the other line is 1 > 1 + 2 false.... so you know the true line... just need to look a the x + 2 line to find the true one

It was A. thank you @campbell_st I used your method :)
