You can simplify the math a little if you keep everything as vectors:

slider = effect("Slider Control")("Slider");
T1 = thisComp.layer("your_track_layer").motionTracker("Tracker 1")("Track Point 1").attachPoint;
T2 = thisComp.layer("your_track_layer").motionTracker("Tracker 1")("Track Point 2").attachPoint;
T1 + normalize(T1-T2)*slider
