A graph is shown belowWhich of the following inequalities is best represented by this graph? A,x − 2y > 3 B.x − 2y < 3 C.2x − y > 3D.2x − y < 3

we have that

using a graph tool
see the attached figure 

 case A) x − 2y > 3
this inequality represented the graph

case B) x − 2y < 3
this inequality not represented the graph

case C) 2x − y > 3
this inequality not represented the graph

case D) 2x − y < 3
this inequality not represented the graph

the answer is
the option A, x − 2y > 3
