Question: Find the distance from the origin to the line x=1+t, y=2-t, z=-1+2t(adsbygoogle = window.adsbygoogle || []).push({});

Equations: r = r0 +tv

Attempt:

I think I solved for the vector line equation correctly:

r = < 1, 2, -1> + t< 0, -1, 2>

But I don't know where to go from there. Help please!
