Linus has a utility function U( x, y,) = x + 3y
a) Draw an indifference curve passing through the point (x ,y) = (3, 3), then draw an indifference curve connecting ever bundle such that U = 6.
b) What is an equation the describes Linus's budget if px= 1, py = 2, and income is 8. Add this line to your graph in part a).
c) What bundle would Linus choose if prices change to if px= 1, py = 4, and income is 8.
