In 2004 there were 6675 hybrid vehicles in use.
In 2007, there were 7166 hybrid vehicles in use.
---------------------------------------------------------
Find the equation describing the relationship between time and number of hybrid vehicles. Make sure you use ordered pairs of the form (years past 1998, number of vehicles)
----------------
Pairs: (6,6675) (9,7166)
slope = (7166-6675)/(9-6) = 163.67
intercept: 7166 = 163.67*9 + b; b = 5293
----------------------------
EQUATION:
Y= 163.67x + 5293
-------------------
