Vector $\vec v=(x,y)$ and $||\vec v||= 2$. **Fill in the blanks to complete the following sentences.** Vector $\vec w=(-2x,-2y)$, so $||\vec w||=$ [[☃ numeric-input 1]]. Vector $\vec z=(-4x,-4y)$, so $||\vec z||=$ [[☃ numeric-input 2]]. **Match each vector defined above to a vector that could be its equivalent.** [[☃ matcher 1]]
