Someone please help with this!

  a) $1000

  b) 5 years

  c) -200; a decrease of $200 in value each year

Step-by-step explanation:

When the age of the computer is 0 years, the graph shows its value to be $1000.

The original cost of the computer is $1000.

__

The graph shows the value is 0 when time is 5 years.

After 5 years, the computer no longer has value.

__

The value decreases 1000 in 5 years, so does so at the rate of $1000/5 = $200 per year.

The slope is -200. It means the value decreases by $200 each year.

Step-by-step explanation:

a) At time 0, the value was $1000, so the computer cost $1000.

b) At time = 5 years, the value is zero.

c) In the first year, the value went from $1000 to $800 in 1 year.

It lost $200 of value, so the slope is -200.

It means the computer loses $200 of value per year.
