Free market: supply and demand graph
I need to graph this question out to obtain further information to answer the rest of the question.
Free market. 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
To find the graph, can I rewrite this in a slope-intercept form? For example, would I assume 'S' and 'D' really are 'y', then work the problem in a slope-intercept form from there?
Thank you in advance for your assistance.
