Answer by josmiceli(19441) (Show Source): You can put this solution on YOUR website!
Plot population on the vertical axis
Plot time in years on the horizontal axis
You are given two points on a straight line:
( -5, 1600 )
( 0, 1000 )
-------------
Use the general point-slope formula to
find the equation
--------------------
In 5 years and 10 months, population drops below 300
------------------
check:
( -5,1600 )
OK
( 0, 1000 )
OK
( 5.8333, 300 )
OK
