How to make 2D aiming line?

I want to make this kind of ball aiming line. I tried to use Raycast and LineRenderer, but it doesnt work. please help me!

         hit = Physics2D.Raycast(transform.position, (JointPoint.transform.position - transform.position).normalized);
 
 
         TargetLine.SetPosition(0, transform.position);
         TargetLine.SetPosition(1, hit.point);
