<PRE><B>Question 508250</B>
--------------------
You have a table with the following: 
n y
2 8
5 5
7 3 
----
Slope between (2,8) and (5,5) is (5-8)/(5-2) = -1
Slope between (5,5) and (7,3) is (3-5)/(7-5) = -1 
What is the linear equation?
Form:
y = mn + b
5 = (-1)5 + b
b = 10
---- 
y = -n + 10
