Follow mouse tutorial question

I’m doing beta’s tutorial on “follow mouse with easing”, and was wondering how I could change the movement.

In his example the MC moves along with the mouse, but how could I make the MC move in the opposite direction of the mouse?

onClipEvent (load) {
    clip._x = 150;
    clip._y = 100;
    speed = 10;
onClipEvent (enterFrame) {
    endX = _root._xmouse;
    endY = _root._ymouse;
    _x += (endX-_x)/speed;
    _y += (endY-_y)/speed;
