V= -2000t +15000
Step-by-step explanation:
Present the information given as coordinate point where, at purchase time, x=0, value of equipment, y=$15000
This is (0,15000).
After depreciating linearly in 5 years, the salvage value, is $5000
This is (5,5000)
Finding the slope of the graph,
m=Δy/Δx
m=5000-15000/5-0
m= -10000/5 = -2000
y-intercept = 15000
The equation in form of V=mt +b where
V=value of equipment after time t
m=slope of the graph
b=y-intercept
Equation ⇒ V= -2000t +15000
