Question 810484: Sales of Plasma TV's in the US were about 1.8 billion in 2000, and 4 billion in 2004. Let t=0 correspond to 2000 and find a model for this data. According to this model, what are sales in 2016?
t=16 corresponds to 2016

You can use the general point-slope formula
The given points are:
( 0, 1.8 ) and ( 4, 4 )
Time in years are plotted on the horizontal axis and
billions of sales are plotted on the vertical axis
--------------

This is ( change in y ) / ( change in x ) = ( change in y ) / ( change in x )

-----------------
You are asked to find the point ( 16, s )

There will be 10.6 billion in sales in 2016
check:

OK
Here's the plot of the line:
