Answer:

A) Price= 1617*Year - 3.116e+006;     B) 150340$ By 2020

Step-by-step explanation:

We have a data set of 7 x, y pairs, this data set can be modelled as line, applying a linear regression calculator we found that the trend line can be modelled as Price= 1617*Year - 3.116e+006  

Attached you will find the regression results where x is the year variable and Y is the price. If we now plug year=2020 in the equation we have:

Price=1617*2020-3.116e+006 = 150340$
