### Understanding Motor Vehicle Crash Deaths Over Time

#### Data on Fatalities
Below are statistics on the number of deaths resulting from motor vehicle crashes across various years. The table provides the corresponding values for specific years, which are coded for ease of plotting:

| Year     | Deaths |
|----------|--------|
| 1975 (x=1)  | 44,533 |
| 1980 (x=6)  | 51,122 |
| 1985 (x=11) | 43,809 |
| 1990 (x=16) | 44,590 |
| 1995 (x=21) | 41,798 |
| 2000 (x=26) | 41,960 |
| 2005 (x=31) | 43,436 |
| 2010 (x=36) | 32,697 |

#### Graphical Representation
You are asked to construct a scatterplot and identify the best mathematical model for the given data. Below are four possible scatterplots for you to choose from:

###### Graph Options:
- **Graph A**
- **Graph B**
- **Graph C**
- **Graph D**

Each graph plots the number of deaths (y-axis) against the coded year (x-axis) and is essential for determining the trend and selecting the appropriate model.

#### Model Selection
Based on the best fit, choose the mathematical model from the options given below and fill in the appropriate constants. Ensure the calculations are precise, rounded to three decimal places as needed.

1. **Model A**: \( y = \_\_\_ x \)
2. **Model B**: \( y = \_\_\_ + (\_\_\_ \ln x) \)
3. **Model C**: \( y = \_\_\_ + (\_\_\_ x) \)
4. **Model D**: \( y = (\_\_\_)^x \)
5. **Model E**: \( y = \_\_\_ x^2 + \_\_\_ x + \_\_\_ \)

#### Projection
Using the best-fit model, the projected number of deaths for the year 2028 needs to be calculated. Fill in the value rounded to the nearest integer.

**Projected number of deaths in year 2028**: \(\_\_\_\)

This exercise helps in understanding the trends over decades and making future predictions based on historical data
