Answer:

-1/6

Step-by-step explanation:

m = (y2-y1)/(x2-x1)

    = (-4-8)/( 1-3)

    = -12/-2

    =6

We want a line perpendicular, so we need the negative reciprocal

Step-by-step explanation:

The percentage change in a value can be computed from ...

  %change = ((new value)/(old value) -1) × 100%

  = ((8500/9559) -1) × 100%

  = (0.8892 -1) × 100%

  = -11.08%

The value of the car decreased about 11.1% in the first year.
