2. Answer:

   given, y≥2x+1 and 

   y>21x−1

   first, draw the graph for equations  y=2x+1 and y=21x−1

   for y=2x+1 

   substitute y=0 we get, 2x+1=0⟹x=−0.5

   substitute x=0 we get, y=1

   therefore, y=2x+1 line passes through (0.5,0) and (0,1) as shown in fig.

   Hence,  y≥2x+1 includes the region above the line.

   for y=21x−1
