An inverse curve is a curve of the general form y = (a/x) + b, where a and b are constants or coefficients. An inverse curve can be plotted as a straight line, which has the general form y = mx + c, where m is the gradient and c is the y-intercept, by calculating the inverse or "reciprocal" of the x coordinates and then replotting them against the original y coordinates. You can straighten a curve to easily determine the coefficients of the inverse curve.
Write down in a table your x and y coordinates.
Plot the x and y points on a graph and draw an inverse curve line of best fit through the points.
