Thank you for the opportunity to help you with your question!
The line on the edge passes through (-1/2,0) and (0,1)
Slope of the line is (1-0)/(0-(-1/2)) =2
The equation of the line is y-1 =2(x-0)
Hence first, second and fourth options are ruled out.
We are interested in y > 2x+1
It must exclude these points.
Y > 2x+1
Third option is
