10. A company purchased a new machine for $120,000 and decided
to depreciate the machine using linear depreciation over 10 years
(when the salvage value becomes 0). Write the linear model f(x) =
mx+b that expresses the salvage value of the machine in thousands
of dollars in x years;
also give the domain and graph the grid below.

Write a linear model f(x) = mx + b that expresses the salvage value of the machine in thousands of dollars in x years; give also its domain, then graph on the grid below. What is the salvage value of the machine in 3 years? In how many years will the salvage value of the machine be $72,000? (Remark: as the values of f(x) are in thousands, the coefficients m and b cannot involve thousands!)
