Answer to Question 1

False. Indifference curves for perfect substitutes are parallel lines, but the slope is not necessarily negative one.

Answer to Question 2

False. While indifference curves are typically convex, they can be concave. This means, however, that the MRS of y for x increases as x increases. That is, the consumer places greater value on the next x the more x she has. The interpretation is that a consumer with concave indifference curves prefers to specialize in either x or y but not have a mix of both.
