## Question:

Assume the price of good {eq}X {/eq} is {eq}P_x {/eq}, the price of good {eq}Y {/eq} is {eq}P_y {/eq}, and {eq}B {/eq} is the budget. The formula for the budget line for these two goods is:

a. {eq}P_yQ_y/P_xQ_x {/eq}

b. {eq}P_yB + P_yB = B {/eq}

c. {eq}P_xX + P_yY = B {/eq}

d. {eq}(1 - P_y/B)P_x {/eq}

## Indifference curve

Indifference curve is the curve or graphical representation of the different levels of consumer satisfaction. The curve is generally convex for normal goods. Indifference curve is also paired with budget line, to know at what budget the consumer can purchase at the particular level of satisfaction.
