Answer:
b. The slope of the budget constraint is the same for each woman.
Explanation:
Budget Line is the combination of two goods that a consumer can buy, given prices & money income (all spent). 
Equation : p1x1 + p2x2 = m ; 
where p1 & p2 are price of good 1 & 2 , x1 & x2 are quantities of good 1 & good 2 , m = money income  
- Abby's Budget Line : 5I + 8N = 80 
- Bobbi's Budget Line : 5I + 8N = 60 
- Deborah's Budget Line : 5I + 8N = 40 [ I = Icecream, N = Novel ]  
Slope of Budget Line represents change (sacrifise) of a good needed to get change (gain) of other good, given same prices & income.
Slope = ΔY/ΔX = Px / Py 
Since prices are same for each woman, price ratios & hence the slope of budget line will also be same for all of them.

Answer:
The number of check-ups in this market would decrease.
Explanation:
This is an example of price ceiling.  
Price ceiling refers to a legal maximum price that is set by the government for a commodity to be sold. 
Price ceiling set below the equilibrium price will result in a supply shortage as it will be effective and binding, while price ceiling set above the equilibrium price will not affect quantity supplied in the market as it will not be effective and binding.
Since the $40 price of heck-up is below $50 equilibrium price, it will result in shortage supply and the number of check-ups in this market would decrease.
