Question 1163567
The book value of a machine is expressed by the equation V=80000-8500t, where V equals the book value in dollars and t equals the age of the machine expressed in years.
• Identify the t and V intercepts.
The t intercept occurs when V=0
-8500t + 80000 = 0
-8500t = -80000
t = -80000/-8500
t = 9.412 is t intercept
The V intercept occurs when t=0
V = -8500(0)+80000
V = 80000 is the V intercept
:
• Interpret the meaning of intercepts.
t = 9.412 yrs, the value of the machine drops to 0
v = $80000 the initial value of the machine (t=0)
:
• Interpret the meaning of slope.
slope is -8500, is the amt the value is reduced each year
:
• Sketch the functions.
t is the  x axis, V is the y axis
{{{ graph( 300, 200, -6, 15, -10000, 90000, -8500x+80000) }}}


(ii) - For the equations mention below:
What equations???
• Determine x intercept and y intercept.
• Determine slope.
• Sketch the graph at X=(-2, -1 ,0, 1, 2)
