Let's call the position of the mouse click on the stage (clickedX, clickedY) The starting coordinates are (startX, startY) The ending coordinates are (endX , endY)
The general equation of your line, for any variables X and Y, is: Y == (X - startX) * (endY - startY) / (endX - startX) So when the user clicks on the stage, the values of clickedX and clickedY would need to satisfy the following equation: clickedY == (clickedX - startX) * (endY - startY) / (endX - startX) If this is true for clickedX and clickedY then that means the click fell on the line. Of course you would probably have to provide a bit of an error margin because you can't accurately evaluate the equality (==) of real numbers.
