ganeshie8 · Answer

so you want to find component form for AB

ganeshie8 · Answer

in going from A to B, you are going 12 units right in x direction
so x component is 12

ganeshie8 · Answer

similarly y component is 5
so component for for rayAB  =  <12, 5>

ganeshie8 · Answer

you can use this formula :

$<x2-x1,\ y2-y1>$

where, (x1, y1) is the initial point, and (x2, y2) is the terminal point
