Answer:
if two quantities x and y vary (change) in such a manner that an increase in x causes a proportional decrease in y (and vice versa), then x and y are said to be inverse proportion. If x and y are in an inverse variation, then xy = constant. The value of a variable is not constant and keeps on changing.
