Both of the inequalities  have negative slopes, but the top two graphs have  a line with a positive slope, so the answer cannot be either of these


Looking at the bottom left  graph,  if this one is correct, the point  (0,4)   should make both inequalities true....but notice that this would mean that  4  < (-1/2) (0)  + 2 ⇒  4 < 2     which isn't true


So......the bottom right graph must be correct.....



cool cool cool
