Thread: Linear equation

A small business purchases equipment for $1000. After 10 years the salvage value will be $200. Write a linear equation for the value v of the equipment during its 10 years of use. (use straight line depreciation with t=0 when the equipment is purchased)

(time in years ,value in $)

you have two sets of coordinates (t , v) ...

(0,1000) and (10,200)

find the slope between the two points and find as a linear function of
