Suppose I have a set of XY coordinates (pink dots including noise)which is a measured values of a line segment (Black line). After estimating the best line (Orange line) for the measured data points, how can I calculate the accuracy of the fitted line with the actual one.

You can get the residuals and use R or R^2 or the sum of absolute differences. R squared is a pretty common metric - why not use that?
