1. Let's get some practice plotting budget constraints. On the graph below, plot the budget constraints when:
a. (Use Black): P_{x} = 57,P_{y} = 18, and M = 342.
b. (Use Blue): P_{x}/P_{y} =4/5 and M/P_{y} = 20.
c. (Use Red): M/P_{x} = 14 and M/Py = 16.
d. (Use Pencil): P_{x}/P_{y} =4/5 and the bundle (19, 16) is on the boundary of the feasible set.
