Answer:
sqrt(13)
All vectors here have the same magnitude because they are the same vector, just moved around.
Explanation:
Vector v goes from(-3,-4) to (-1, -1) to find the vector you simply find the difference of each coordinate <-1 - -3, -1 - -4> = <-1+3, -1+4> = <2,3>
All vectors here are the same, just moved around, so they have the same form and magnitude, just a heads up. anyway, magnitude is the distance formula.
sqrt(2^2 + 3^2) = sqrt(13)
