One simple form of a linear equation specifies the starting value and the rate of change (slope):
The slope is m, the starting value is b.
The starting value is 20000.
The change in value is from 20000 to 2600 in 10 years. That's a change of -17400 in 10 years, a rate of -17400/10 = -1740 per year. So
where y is the value and x is the time in years since the purchase.
Your post says "select" a linear equation, but you don't show the choices.
Find one which is equivalent to the one shown.
