Answer 1

$\huge\pink{\mathfrak{answer}}$

The marginal rate of substitution (MRS) is the slope of the indifference curve. ... For the downward-sloping convex indifference curves which result from well- behaved preferences, the MRS is always negative, and always decreases (becomes greater in absolute value) as the amount of good x decreases.
