(a) Assuming that the change was linear, write the equation(in Slope-Intercept Form) of the relationship where y is the sales (in thousands of dollars) and x is the time in years. Hint: It is better to consider 2000 as "year 0"(year zero) and write the first ordered pair as (0, 176) where the "176" is the sales in thousands of dollars.

The slope is 125/10.
dbospj wrote:B) I figured the sales per year increases because it's steeper than the identity line?

dbospj wrote:D) I'm not sure how to write an equation for this?
dbospj wrote:Oh I used the wrong number in the equation for C. The predicted sale amount would be $ 363,500.
