Question 3
A vector has initial point ($-9, 19$) and terminal point ($-9, -14$).
The component form of the vector is:
Question 4
The vector $<2, -6>$ has terminal point ($-11, 7$).
The initial point of the vector is:
Question 5
Let $\vec{a} = (1, -9)$ and $\vec{b} = (2, -6)$.
The dot product is $\vec{a} \cdot \vec{b} =$
Question 6
Let $\vec{a} = (8, -7)$ and $\vec{b} = (3, -2)$.
The dot product is $\vec{a} \cdot \vec{b} =$
