Question 401388: The equations S = 5000 + 200x and D = 9500 – 100x express the supply S and the demand D, respectively, for a popular compact disc brand in terms of its price x (in dollars).
a) Graph the equations on the same coordinate system.
b) What happens to the supply as the price increases?
c) What happens to the demand as the price increases?
d) The price at which supply and demand are equal is called the equilibrium price. What is the equilibrium price?

S = 5000 + 200x and D = 9500 – 100x
...


Red line = supply
supply increases as price increase
...
Green line = demand
demand declines as x increases.
..
Equilibrium price = $15
