When a variable y is inversely proportional to a variable x, the graph when y is plotted against x takes on the shape of a hyperbola.
To linearize the graph plot y against 1/x instead of y against x.
For instance, if y is inversely proportional to x and the two are plotted the resulting graph is of the form:
The graph can be linearized by plotting y against 1/x. The resulting graph is of the form:
