Find the slope of the line through the points (4, 7) and (-3, 7).

Count the rise and run between the two given points. What is the slope of the line?

A. [tex] m = 6 [/tex]
B. [tex] m = 1 [/tex]
C. [tex] m = 0 [/tex]
D. [tex] m = \text{undefined} [/tex]



Answer :

To find the slope of the line through the given points [tex]\((-8, 6)\)[/tex] and [tex]\((4, 6)\)[/tex], we'll follow these steps meticulously.

### Step 1: Understand the Coordinates

We have two points:
- [tex]\( (x1, y1) = (-8, 6) \)[/tex]
- [tex]\( (x2, y2) = (4, 6) \)[/tex]

### Step 2: Calculate the Rise and Run

- Rise: This is the change in [tex]\(y\)[/tex]-coordinates.
[tex]\[ \text{Rise} = y2 - y1 = 6 - 6 = 0 \][/tex]

- Run: This is the change in [tex]\(x\)[/tex]-coordinates.
[tex]\[ \text{Run} = x2 - x1 = 4 - (-8) = 4 + 8 = 12 \][/tex]

### Step 3: Calculate the Slope

The slope [tex]\(m\)[/tex] of a line is given by the formula:
[tex]\[ m = \frac{\text{rise}}{\text{run}} \][/tex]

Plugging in our values:
[tex]\[ m = \frac{0}{12} = 0 \][/tex]

### Conclusion

The slope [tex]\(m\)[/tex] of the line through the points [tex]\((-8, 6)\)[/tex] and [tex]\((4, 6)\)[/tex] is [tex]\(0\)[/tex]. This indicates a horizontal line with zero slope.

So the correct answer is:
- [tex]\(\boxed{0}\)[/tex]

The computed slope confirms that the multiple choice option [tex]\(m = 0\)[/tex] is the correct answer.
