Question 260179: A salesman for an electronics company finds that the number of mp3 players that he can sell during a month depends on the price. When they are priced at $100, he can sell 50 of them. When the price drops to $50, he can sell 250 of them. Write a linear equation in the form p = mn + b, where n represents the number sold and p represents the price, that reflects this (and m is the slope and b is the p-intercept).

p-p/n-n=m
250-50/50-100
200/-50=-4
p=mn+b
50=-4*100+b
50=-400+b
350=b
p=-4n+350
