Straight line method assumes a gradual depreciation in value of an asset's useful life.
-It's calculated by dividing the difference between an asset's cost and its expected salvage value by the number of years it is expected to be used.

Accumulated depreciation=8*2000=$16,000
1) graphs y = -9x + 12 and y = 1/3x - 12 are not coincident.
2) The graphs are not parallel, because the angular coefficients are not equal
3) The condition of perpendicularity:
, where
- not perpendicular
