Linear Functions problem

Question

The population of a city increased from 21,300 to 31,300 between 2003 and 2008. Find the change of population per year if we assume the change was constant from 2003 and 2008.

 

The population increased by_______ people per year?

Answer 1

here we have to find constant change(slope)

 

(31300 -21300 ) /( 2008-2003) = 10000 /5 = 2000

 

The population increased by 2000 people per year
