Answer:
Graph # 3
Step-by-step explanation:
-2x + 5y > 15               Let x  = 0  solve for y 
  -2(0) + 5y = 15             change the > to an = 
      5y = 15
       y =3     Point (0, 5) is on the graph
  Graph # 3 is correct because the y-intercept  is 5  
     x          y
     0          3                    -2(0) + 5y = 15;     5y = 15
     5          5                  -2(5) + 5y = 15;    -10 + 5y = 15;  5y = 25; y = 5
     10         7                   -2(10) + 5y = 15; -20 + 5y = 15; 5y = 35; y = 7
    The graph > the line is dotted and you will shade above the line
