Vector $\vec { \text{b} }$ has an initial point of $\left(−1, 0\right)$ and an endpoint of $\left(2, 2\right)$.  

1. Express $\vec { \text{b} }$ in component form.

   Hint (a):

   Graph the vector. Use the graph to determine the horizontal and vertical components.

2. Sketch $\vec { \text{b} }$, $3\vec{\text{b}}$, and $\frac{1}{2}\vec{\text{b}}$.

   Hint (b):

   Each of these vectors has the same direction, but a different magnitude.

3. Write a unit vector that has the same direction as $\vec { \text{b} }$.

   Hint (c):

   Determine the magnitude/length of vector $\text{b}$. Then divide each of the components of vector $\text{b}$ by its length.
