Calculate the slope between each point, if you dont get the same slope, its not a straight line, therefore not directly proportional.
The answer is 56,700
If you take 7500 and divide it by 100 than multiply by 7 you get 525 and multiply 525 by 12 you get 6,300 than 6,300 multiplied by those 9 years you get 56,700
