Consider the line $L$ defined by the following parametric equations

$$x= 3+2t$$ $$y= 4+t$$ $$z=5-6t$$

Find the point $Q$ on $L$ that is closest to $(4,1,7)$.

Note: I do not really remember the formulas, I need help!

    @marvis There has been strong [consensus on meta in the past](http://meta.math.stackexchange.com/questions/1617/what-is-the-site-etiquette-about-i-asking-and-ii-answering-questions-in-a-la) that people generally prefer coherent questions in foreign languages, which can be intelligently translated to English (as this one was) to incoherent, unintelligible questions in English.2012-06-25
