Given the points (-2,-6) and (0,5), you can identify that:

Therefore, substituting values, you get that the distance between those points is:

Independent quantity (x) is number of races won
dependent quantity f(x)...or y is total virtual money
the function is : f(x) = 500x + 5000 or y = 500x + 5000
Can you give the choices please
