Question 797555
Suppose the birth rate among teenagers in a certain country, measured in births per 1000 females age 15-19, fell steadily from 62.3 in 1992 to 41.3 in 2005
------------------
graph the given data and determine an equation for the related line then use the equation to answer parts (a) and (b)
------------------
You have 2 points: (1992,62.3) and (2005,41.3)
-----
slope = (41.3-62.3)/13 = -21/13
----
Form:: y = mx + b
41.3 = (-21/13)(2005) + b
b = 3280.15
----
Equation:
f(x) = (-21/13)x + 3280.15
============================

(a) calculate the birth rate among teenagers in 1999
f(1999) = 50.99
--------------------
(b) Predict the birth rate among teenagers in 2009
f(2009) = 24.84
