![### Educational Resource on Linear Combinations of Vectors
### Problem Statement
Use the accompanying figure to write each vector listed as a linear combination of vectors **u** and **v**.
Vectors **b**, **w**, **x**, and **y**
![Vector Diagram](image_url)
**Write **b** as a linear combination of **u** and **v**.**
\[ \mathbf{b} = (\_\_\_\_) \mathbf{u} + (\_\_\_\_) \mathbf{v} \]
(Type integers or decimals.)
### Explanation of the Diagram
The diagram provided in the figure consists of vectors with their linear combinations represented on a grid. Each vector is positioned relative to vectors **u** and **v** along their respective axes.
We see a central origin point **0** with the following vectors and positions in relation to **u** and **v**:
- **u**: A unit vector along the positive x-axis.
- **v**: A unit vector along the positive y-axis.
- **b**: Positioned at the intersection of the grid lines representing 0.5 units of **u** and 1 unit of **v**.
Some other vectors shown for reference are:
- **d**, **c**, **a**: Various other vector positions.
- **w**, **x**, **y**, **z**: Other vectors to be expressed as combinations of **u** and **v**.
### Example Calculation
#### Vector **b**
To express vector **b** as a linear combination of **u** and **v**:
1. **b** is located at a point which, in terms of vector addition, can be represented as:
- **0.5** units in the direction of **u** (along the x-axis).
- **1** unit in the direction of **v** (along the y-axis).
Thus, vector **b** can be written as:
\[ \mathbf{b} = 0.5 \mathbf{u} + 1 \mathbf{v} \]
### Interactive Component
You can now type the values into the provided fields to check your understanding:
\[ \mathbf{b} = (\_\_\_\_) \mathbf{u} + (\_\_\_\_) \mathbf{v} \]
Remember to type integers or decimals.
