turingtest · Answer

exactly :)
how do we know which one?
by asking "is it shaded above or below the line"
if it is shaded below it is $y\le...$
if it is shaded above it is $y\ge...$
so now which is the answer?

turingtest · Answer

below the dark line with y-intercept 7 that we are talking about are the yellow and green regions
