Using Straight Line Graphs From Data to Determine Functions

The pairs of (x,y) values in Columns A & B result in points lying on a curve. Calculate the value of y/x for each pair (done in column C, check only) Plot y/x vs x to get a set of points which lie on a straight line. The equation (or function) of a straight line can be found by first determining the gradient and the y intercept. Discuss how you can determine the function of the curve using the equation of the straight line.
