Pre Cal math problem? - is there a j c penney store on maui
In 1996 there were 3927 JC Penney stores and in 2000, had 3800 stores. Write a linear equation with the number of transactions in respect of the years. T = 0 represent 1996th Then predict the number of transactions for the years 2005 and 2010.

This is often the case when the value of x. In a chart, the x-axis 1996 and 2000 in it. The tree has that 3927 and 3800th
(x2 - x1) / (y2 - y1)
(3800 - 3927) / (2000 - 1996)
-127 / 4, the slope is
y = (-127 / 4) x + b
Since 1996, t = 0 intercept, and (b) 3927.
The years 2005 and 2010 were 9 or 14 years from 1996.
y = (-127 / 4) x + 3927
y = (-127 / 4) (9) + 3927
and = 3641
y = (-127 / 4) (14) + 3927
y = 3483
Two ways to write a linear equation EQUASION linear form, where
y = mx + b, where m = slope b = intercept.
or
m = (y2 - y1) / (x2-x1)
In this case, the variable t (time) is the value of X (independent variable) and the number of branches of the Y, or the value of the dependent variables. You have two points, then use the second equation.
m = (3800 - 3927) / (4-0), 4-0, can use up to 1996 or 2000, but the problem into the well and in 1996 for the use of 4-0.
It works with m = -127 / 4.
Since 1996, the axis, we know that the origin is 3927, then intercept the slope, we obtain
y = (-127 / 4) t + 3927
By 2005, 2005 to 1996 = 9 t = Y = 3641.25
In 2010, T from 2010 to 1996 = = 14 = 3482.5 so that it
