In 2002, crude oil production by OPEC countries was 36 million barrels per day. in 2006 OPEC crude oil production had risen to about 48 ?

Time is typically on the 'x' axis. Adjust for 2000 as the origin, this is the tricky part of the problem!

(2, 36), (6, 48)

Slope 'm' is ∆y/∆x = (48-36)/(6-2) = 3

y = mx + b

y = 3x + b

Insert one of the pairs above to solve for 'b'

36 = 3(2) +b

b = 30

So equation is y = 3x +30

 In 2002, crude oil production by OPEC countries was 36 million barrels per day. 

 In 2006 OPEC crude oil production had risen to about 48 million barrels per day. 

 Let x be years after 2000 and 

 ley y be crude oil production in millions of barrels per day.   A.  write two ordered pairs for this model.  should be in (X,Y)  (years after 2000, crude oil production in millions of barrels per day. B.  Assume that the relationship between x and y is linear.  using the ordered pairs listed in part A write a linear equation relating to x and y
