Question 797555: Cant wrap my head around this one either folks. I am just not that great at doing algebra in my head and word problems makes it worse if any one could help and help me understand the quagmire it would be great..right now i think the answer is purple because aliens do not wear hats....
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)
(a) calculate the birth rate among teenagers in 1999
(b) Predict the birth rate among teenagers in 2009

You can put this solution on YOUR website! 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
==================
