Select all the statements that are true for the graph shown.

Transcribed Image Text:### Submarine's Descent Graph
The graph titled "Submarine's Descent" illustrates the relationship between time and the submarine's height above sea level.
#### Axes:
- **X-axis (Horizontal):** Represents time in seconds (sec), ranging from 0 to 6.
- **Y-axis (Vertical):** Denotes height above sea level in feet (ft), ranging from 0 to -16.
#### Graph Details:
- The graph features a straight line with a negative slope, indicating a consistent descent of the submarine over time.
- The line begins at point (0, 0), where the submarine starts at sea level, and ends at approximately point (6, -16).
- The labeled points "x" and "y" assist in denoting axis directions; "x" for the horizontal time axis and "y" for the vertical height axis.
#### Interpretation:
- At 0 seconds, the submarine is at sea level (0 feet).
- By 6 seconds, the submarine has reached a depth of -16 feet, showing a uniform descent rate.
- The line's uniform descent suggests a constant speed of descent over the observed period.
This graph is helpful for understanding the concept of linear relationships and rates of change in real-world scenarios, such as underwater vehicle movement.

Transcribed Image Text:The image displays a series of audio buttons with corresponding text related to linear equations and graphing concepts:
1. **Audio Button**:
- Text: "The relationship is proportional."
2. **Audio Button**:
- Text: "The slope is −6."
3. **Audio Button**:
- Text: "The slope is negative."
4. **Audio Button**:
- Text: "The y-intercept is −3."
5. **Audio Button**:
- Text: "The equation of the line is y = −3x."
There are no graphs or diagrams in this section. The text appears to relate to learning objectives about understanding linear equations, specifically focusing on slope, intercepts, and proportional relationships.
