Transcribed Image Text:The graph illustrates the average mileage for Electric Vehicles (EV) and Gasoline Vehicles from 2010 to 2021. It uses two sets of data points: blue for EVs and red for gasoline vehicles, with corresponding linear trend lines.
**Graph Details:**
- **X-axis**: Represents the year, ranging from 2010 to 2022.
- **Y-axis**: Shows mileage, with values from 0 to 450.
**Data Points and Trend Lines:**
- **Electric Vehicles (EVs)**:
- Represented by blue dots.
- The trend shows a gradual increase in average mileage over the years.
- The linear trend line is denoted by a blue dashed line with the equation \( y = 14.927x - 29938 \).
- **Gasoline Vehicles**:
- Represented by red dots.
- The trend remains relatively stable, with slight variations year over year.
- The linear trend line is denoted by a red dashed line with the equation \( y = 1.4273x - 2490.7 \).
Overall, the graph indicates that while EVs started with lower average mileage, they have been increasing steadily, whereas gasoline vehicles have shown minimal variation in average mileage over the same period.
