can you give me an explanation?

Solve the system graphically, and indicate whether the solution region is bounded or unbounded. Find the coordinates of each corner point. 2x+y210 x+3y215 x20 y20 Use the graphing tool to graph the system of inequalities. Graph the region that represents the correct solution only once. Click to enlarge graph The solution region is E because the shaded region IE be enclosed within a circle. What are the coordinates of each corner point? E (Type an ordered pair. Use a comma to separate answers as needed.)
