Webx is directly proportional to y: x = ky x is inversely proportional to y: x = k/y That's all you really need to know... k is a constant. When they ask you to write the formula for proportion, you always have to work out k. For example, for the first one, if they say when x is 100, y = 50. 100 = 50k k = 100/50 = 2 x = 2y Reply 2 14 years ago
