Anyone have any idea on how I would do this? (Bezier Curves)

Alright, so basically I've managed to finish programming basic bezier curve stuff but it works based on points already in place, I would have to place each point one at a time. What I'm attempting to do is generate a bezier curve based on a start position and an end position(2 points) and have a curve instead of a straight line such as raycasting from both points.

If anyone has any idea on how I would do this please respond!
