Weby is inversely proportional to x. y varies inversely as x. y and x are inversely proportional. y ∝ 1/x; y ∝ x −1; For example… The time needed to finish a job varies inversely as the number of workers. More workers means less time to finish a job. (Twice as many means it takes half the time.) Fewer workers means it takes longer. WebDirectly proportional means if x has a certain value, y should have the same value. but here in the graph, when x is 0, y has a value greater than 0. for x and y to be directly proportional, the line should go through 0.
