The demand for coffee is given by the following equation, where QD stands for the quantity demanded and P stands for price.
QD = 100  4P
The supply of coffee is given by the following equation, where QS stands for the quantity supplied and P stands for price.
QS = 10 + 2P
6.
value:

The supply of coffee is given by the following equation, where QS stands for the quantity supplied and P stands for price.
QS = 10 + 2P
Solution:
a. What is the slope of demand? Slope = 4
b. At what price is quantity demanded equal to zero? P = 25
c. What is the slope of supply?
Slope = 2
d. At what price is quantity supplied equal to zero?
P = 5
e. In the diagram below use the line tool to plot the demand and supply curves using the original equations and your values for the intercepts and slopes of each equation.
QD = QS
1004p = 10+2p
P = 15
The intercept is (15, 40)
