Question 820928
Identify two (x,y) data points.  You are interested in count of years since 1990.

(0, 97200) and  (8, 115600)


If you are comfortable enough with the slope-intercept form of a line, then you know what to do.


Briefly, you can use this:  {{{m=(115600-97200)/(8-0)}}} and then pick either point to solve {{{b=y-mx}}}.
