To graph the solution set, first, we know that the border of the shaded area will be delimited by the dashed line:
[tex]-2x+5y=15.[/tex]
Now, to know if the shaded area will be on top or below the line, we evaluate the point (0,0):
[tex]-2(0)+5(0)=0<15,[/tex]
therefore, the origin is not a point of the solution set.
