WebAll direct proportion graphs must start at the origin. For example, If y y is directly proportional to x x then the graph will be a straight line. If y y is directly proportional to a function of x x such as x^ {2} x2 or \sqrt {x} x then the graph will form a curve. For inverse proportion, as one variable increases the other variable decreases. 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.
