@TurdPile: The x values are the linear scale values, and the y values are the logarithmic scale values. You asked to convert linear to logarithmic, and you just plug the numbers into the formula. In this case, the linear input of 5.00 would become 1.02 on the logarithmic scale. – Dietrich Epp Oct 20 '13 at 5:51

Since both axes are transformed the same way, the graph is linear on both sets of axes. But when you fit the data, the two fits will not be quite identical. Slope is the change in log(Y) when the log(X) changes by 1.0. Yintercept is the Y value when log(X) equals 0.0. So it is the Y value when X equals 1.0. An alternative way to handle these data
Linearization of exponential growth and inflation: T he logarithm of a product equals the sum of the logarithms, i.e., LOG(XY) = LOG(X) + LOG(Y), regardless of the logarithm base. Therefore, logging converts multiplicative relationships to additive relationships, and by the same token it converts exponential (compound growth) trends to linear trends.

The term on the right-hand-side is the percent change in X, and the term on the left-hand-side is the unit change in Y.. In economics, many situations are characterized by diminishing marginal returns. The linear-log model usually works well in situations where the effect of X on Y always retains the same sign (positive or negative) but its impact decreases.
