Draw a Line From any Point A To any Point B Dynamically Using AS3

Question

I am trying to make an anmation where there are several locations(say A,B,C,D,......) made on a  map. If a person clicks on one location A and then another location B, I wanted to draw a dotted line from point A (from  destination of the plane) to point B(to destination of the plane)  using AS3. Please help me........

Here is a quick and dirty timeline code that does it (class is below):
var line:Shape;
var lineGraphics:Graphics;
var clickSwitch:int = 0;
var mousePositions:Array = [];
var conversion:Number = 180 / Math.PI;
init();
function init():void {
     drawBackground();
     line = new Shape();
     addChild(line);
     lineGraphics = line.graphics;
     stage.addEventListener(MouseEvent.CLICK, onClick);
function onClick(e:MouseEvent):void
     clickSwitch = 1 - clickSwitch;
     mousePositions[clickSwitch] = new Point(mouseX, mouseY);
     if (clickSwitch == 0) {
          drawLine();
     else {
          removeLine();
function removeLine():void
     lineGraphics.clear();
     line.rotation = 0;
function drawLine():void
     lineGraphics.lineStyle(1, 0xff0000);
     lineGraphics.moveTo(0, 0);
     var dotDistance:Number = 2;
     var nextX:Number = dotDistance;
     while (line.width < Point.distance(mousePositions[0], mousePositions[1])) {
          lineGraphics.lineTo(nextX, 0);
          nextX += dotDistance;
          lineGraphics.moveTo(nextX, 0);
          nextX += dotDistance;
     line.rotation =  conversion * Math.atan2(mousePositions[0].y - mousePositions[1].y, mousePositions[0].x - mousePositions[1].x);
     line.x = mousePositions[1].x;
     line.y = mousePositions[1].y;
function drawBackground():void
     var s:Shape = new Shape();
     var g:Graphics = s.graphics;
     g.beginFill(0xC0C0C0);
     g.drawRect(0, 0, stage.stageWidth, stage.stageHeight);
     g.endFill();
     addChild(s);
