Midpoint Formula

Question

A soda company had sales of $35,109 million in 2010 and $45,994 million in 2014. Use the Midpoint Formula to estimate the sales in 2012. Assume that the sales followed a linear pattern. 

Answer 1

The midpoint formula finds the midpoint between two other points (ordered pairs). The formula is:

Midpoint = ( (x₁+x₂)/2, (y₁+y₂)/2 )

where (x_1,y₁) = (2010,$35,109 million) and (x₂,y₂) = (2014,$45,994 million). Plug in the numbers and compute the answer.
