Question 731199: Hello,
I need some help graphing supply and demand equations.
Supply curve - P = $10 + $0.25Qs
Demand curve = P = $85 - $0.5Qd
I have calculated the equilibrium quantity at Q =100.
Can any one give me a hint on how to find the coordinates for the graph?(supply and demand curves from the equations above)
I will be grateful for any help.

-----
S(x) = 10 + 0.25x
If x = 4, y = 11
If x = 8, y = 12
-------------------------
D(x) = 85 - 0.50x
If x = 4, y = 83
If x = 8, y = 81
-------------------------

Plot on the horizontal axis, and
plot for both supply and demand
on the vertical axis.
They are straight lines. You can write them as:
( supply )
( demand )
---------------------
Here are the plots:

Note that
( supply )
( demand )
