Question 1143855
A school district purchases a high volume printer, copier, and scanner for $25,000.
 After 10 years, equipment all had to be replaced.
 It’s value at that time is expected to be $2000.
 Write a linear equation giving the value of the equipment for each year tea during its 10 years of use. 
:
Let y the value of the printer after x years
x1 = 0, y1 = 25000
x2 = 10, y2 = 2000
Slope (m): = {{{(25000-2000)/(0-10)}}} = 23000/-10 = -2300
:
the point/slope form y - y1 = m(x - x1)
y - 25000 = -2300(x-0)
y = -2300x + 25000
