how i can change value By UI slider !!

I created an ui slider and i have touch script and sensetivity x , sensetivity Y Variables , and i want control in this variables by slider .

My script :

      var sensitivityX = 13.5f;
     var sensitivityY = 13.5f;
     
     var invertX = true;
     var invertY = true;
     
 
     
         
     function Awake(){
     
     sensitivityX = 5.5f;
      sensitivityY = 5.5f;
     
     }    
     
     // Update is called once per frame
     function Update () {
     
 
 
 
     
         if (Input.touches.Length > 0)
         {
             if (Input.touches[0].phase == TouchPhase.Moved)
             {
                 var delta : Vector2  = Input.touches[0].deltaPosition;
                  var rotationZ = delta.x * sensitivityX * Time.deltaTime;
                  rotationZ = invertX ? rotationZ : rotationZ * -1;
                 var  rotationX = delta.y * sensitivityY * Time.deltaTime;
                   rotationX = invertY ? rotationX : rotationX * -1;
                 
                 transform.localEulerAngles += new Vector3(rotationX, rotationZ, 0);
             }
         }
     }
