.

The slope = %2815000+-+2600%29%2F8 = 1550.


The formula is  P(t) = 15000 - 1550*t,  where t is elapsed time in years.

Problem description is written badly.

Maybe this is something like what it should be:
A computer system is 15000 dollars in value when new, and depreciates to 2600 dollars in eight years. Assuming the value depreciation is linear with time, P=MT%2Bb for P being value, T being time passage in years, find the equation in this form.

M, obviously the slope;
M=%282600-15000%29%2F8=-1550

A known point (T, P) is (0, 15000).
That shows the vertical axis intercept.
