Is it just me or does it seem like all the vectors in my linear algebra class are from the origion...

iguess what im trying to say is...

how would u have a vector going through, lets say 4 on the x axis with a slope of 2?

Results 1 to 6 of 6

ok so say a line ran thru 4 on the x axis and had a slope of 2... could you write that as a vector??

and as for

"The reason for this origin only business is because vectors only have a length and a direction, so they can be moved all over the plane, or in space"

that would be a vector in the subspace... correct?

Yeah we're in a vector space here

Um, idk about your intercept slope question in like a matrix form

Let's say we're on the plane, then via calc 3 and vector based functions we can go with

[x,y]=[t,2t+4]

But in a column vector I don't think you can, or it isn't standard at least
