    Question is still incomplete.. Have you got any Direct or Indirect Variation Case for this question??

    Assume that y varies inversely as x.

    y varies inversely with x means : when y increases, x decreases and when y decreases x increases..

    You can show this variation as: \[y = \frac{k}{x} ; k = constant\]

    when you will put y=-7.5 and x =25 in the above equation you will get the k

    so we get k=-187.5 now put x =5 and k = -187.5 into the above equation and get the y
