# Math Help - Vectors

1. ## Vectors

Dear forum members,

please help me verify if the vectors $\vec{a}=4i+3j$ and $\vec{b}=\frac{-1}{3}i+\frac{-1}{4}j$ are parrallel. $\frac{-1}{12}*\vec{a}=\vec{b}$ So, does this prove they are parrallel?

2. Yes it does. $k*\vec{a}$ (k being a scaler) only extends, shortens or reverses the vector. The line that the vector is on doesn't change.
