How to draw a line with animation?

Question

I have implemented a game application in which I want to draw a line between two objects. I drew a line between two objects. But I want to draw using animation. Let's say I tell you what kind of animation I should use between two points.

Editing: My controversial question is this: Suppose there are two points, such as the start point (100 100) and the end point (300 300). I can draw a line between these two points, but I want to draw a line with animation. I mean that I can see the beginning of the line from the start point to the end point with 2 seconds duration.please help me about this question.
