WebSep 8, 2016 · Let d be the distance between these two points; by the Pythagorean Theorem, d = ( x A − x B) 2 + ( y A − y B) 2. Since B is at a distance d from A, to move d units from A toward B we add x B − x A to x A and y B − y A to y A to get the new ( x, y) coordinates. To move just 1 unit we want to move 1 d times as far, that is, the point 1 ...
