(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Let A and B be given vectors in the plane R2. Find a formula for the closest point from A to the line along B.

2. Relevant equations

The idea is to derive an equation...

3. The attempt at a solution

The problem above is listed verbatim. I don't know how I would attempt it because I would just look at two vectors and say be able to see which point was closest. In other words, I have no idea how to derive a formula.
