The 
4th selection is appropriate:
  The first line is a dashed line which joins ordered pairs (-2, 1) and (3, 1). The second line is a dashed line and joins ordered pairs (-2, -2) and (3, 3). The portion common above the first line and above the second line is shaded
 
        
        
        
Y        X
80     32
100    x'
80x' = 100*32
80x' = 3200
x' = 3200/80
x' = 320/8
x' = 40
