I need to graph this question out to obtain further information to answer the rest of the question.

The equationsFree market.S=5000+200xandD=9500-100xexpress the supplySand the

demandD, respectively, for a popular compact disc brand in terms of its pricex(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 theequilibrium price. What is the equilibrium

price?

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.
