Answer:
I believe it would be the last table. 
Step-by-step explanation:
A linear function has an equation of y=Mx+b where y and x are the variables but m (the slope) and b are constants. The slope for the last table is -8 as the y values are decreasing by 8 every time you move forward one in the x axis. None of the other tables have a constant slope which means they don’t have straight lines when you graph them. Therefore, the last table would have to be the only one representing a linear function

£7200
In first year depreciates by 20%, that is it is worth 80% of it's original value
80% =  = 0.8
 = 0.8
value after 1 year = 0.8 × £10000 = £8000
In the second year it depreciates by 10% of it's value, that is it is worth 90% of it's value at the end of the first year.
90% =  = 0.9
 = 0.9
value after 2 years = 0.9 × £8000 = £7200
