Find the slope of the line passing through the pair of points or state that the slope is undefined. Then indicate whether the line through the points rises, falls, is horizontal, or is vertical. left parenthesis 7 comma negative 9 right parenthesis(7,−9) and left parenthesis 1 comma negative 9 right parenthesis(1,−9)

To find the slope of the line passing through the points \((7, -9)\) and \((1, -9)\), we use the slope formula:

\[
m = \frac{y_2 - y_1}{x_2 - x_1}
\]

Where:
- \((x_1, y_1) = (7, -9)\)
- \((x_2, y_2) = (1, -9)\)

Substitute these values into the slope formula:

\[
m = \frac{-9 - (-9)}{1 - 7} = \frac{0}{-6} = 0
\]

Since the slope is \(0\), the line is **horizontal**. A horizontal line has a constant \(y\)-value and neither rises nor falls.

### Conclusion:
- **Slope:** \(0\) (since the line is horizontal).
- The line is **horizontal** and does not rise or fall.

1. How do you find the slope of a vertical line?
2. What does a positive slope indicate about the direction of a line?
3. How do you find the equation of a line given two points?
4. What are the characteristics of lines with undefined slopes?
5. Can two points on a vertical line ever have the same \(x\)-coordinates?

**Tip:** A slope of zero always means the line is horizontal, which means the \(y\)-values are the same for all points on the line.

Find the slope of the line passing through the pair of points or state that the slope is undefined. Then indicate whether the line through the points rises, falls, is horizontal, or is vertical. (7,−9) and (1,−9)

Learn how to find the slope of the line passing through the points (7, -9) and (1, -9). This step-by-step solution explains how to use the slope formula, and why the line is horizontal with a slope of 0. Perfect for students in Grades 6-8.
