Answer:
The slope of the budget constraint is -2.
Step-by-step explanation:
There are two goods, X and Y.
The price of Good X is $10 and the price of Good Y is $4.
The price of the second unit of good X is $8.
The slope of the budget line is equal to the ratio of the price of two goods.
Hence, the slope of the budget line
=
=
= -2
The slope of the budget constraint is -2.
