Supply & Demand

[alcornk]

The equation 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)

I have to graph these equations and have no idea how as well as find the equilibrium price.
Please help!

S = 5000 + 200x

D = 9500 - 100x

I have to graph these equations and have no idea how

Rhetorical question: How does anyone manage to get into a calculus course without knowing how to plot two points and draw a line through them ?

These are linear equations.

Linear equations are the easiest equations to graph.

I think that you're probably at the wrong site for help.

Come back to these boards when you can form specific questions about graphing lines.
