How do i dash in a direction an arrow is showing?

Hello, Im making a 2D game and If I put my finger on the display, I want the time to slow down and a arrow should appear. When I release my finger, I want the player to dash in to the direction the arrow was showing. The problem is, i am new in unity and dont know how to do this. I would be so grateful if someone would help me.

Look at Time.timeScale on unity, and look at some more documentation like normalized vector3’s and the direction formula is Vector3 direction = (to - from).normalized; in unity.

Hope this helped
