comment Shortest Vector for which Dot Product = x + 2y = 5. (Strang P21 1.2.26)
Although I can see your point and thank you for that (+1) these seem like a long workaround. But thanks.

Thanks. Although I didn't derive since college this is a great and simple way to solve the problem (more than the calculus-free approach that @user12477 proposed). +1

(1,3) will result in a greater magnitude vector than (1,2). So it can't be.

comment Geometry of perpendicular vectors
Thanks for your vey comprehensive answer. I do the exercise as you suggest, it seems from the results that the orthogonal vectors to both will be the span of precisely {1, 0, -1} and such they'll be a line. Also your definition helps me a lot. Thanks!
