Question
![The image contains four coordinate plane graphs, each showing a linear function. Each graph is accompanied by questions related to determining the slope (m), the y-intercept (b), and any other observations (c) about the line.
**Graph Details:**
1. **Graph 5:**
- A horizontal line is drawn that intersects the x-axis.
- **Questions:**
- a. m = (slope of the line)
- b. (0, ) (y-intercept)
- b = (value of the y-intercept)
- c.
2. **Graph 6:**
- A line with a positive slope is drawn, extending from the bottom left to the top right of the grid.
- **Questions:**
- a. m = (slope of the line)
- b. (0, ) (y-intercept)
- b = (value of the y-intercept)
- c.
3. **Graph 7:**
- A line with a negative slope is drawn, extending from the top left to the bottom right of the grid.
- **Questions:**
- a. m = (slope of the line)
- b. (0, ) (y-intercept)
- b = (value of the y-intercept)
- c.
4. **Graph 8:**
- A vertical line is drawn that intersects the y-axis.
- **Questions:**
- a. m = (slope of the line)
- b. (0, ) (y-intercept)
- b = (value of the y-intercept)
- c.
These activities aim to help students practice identifying and understanding different characteristics of linear functions such as their slopes and intercepts.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F882bd528-64e4-4aaf-8446-62c0039b4078%2F672137cd-3afc-40bc-9c79-b90264f1384c%2Fhy2qfb76_processed.png&w=3840&q=75)
