Make a complete graph of the four inequalities below on the same set of axes.
i. 2y 2x-3
ii. x-2y 2-7
iii. ys-2x+6
iv. -9≤2x+y

a. What type of polygon is formed by the solution of this set of inequalities?
b. Write a convincing argument to justify your answer
c. What are the vertices of the polygon? If your graph is very accurately
drawn, you will be able to determine the points from the graph. If it is
you will need to solve the systems (pairs) of equations that represent the
corners of your graphs.
