### Graphing Perpendicular Lines

#### Instructions:
To graph a line that is perpendicular to a given line, follow these steps:

1. **Identify the Slope of the Given Line:**
   - Determine the slope of the given line by finding the rise over run (change in y over change in x) between two points on the line.

2. **Calculate the Slope of the Perpendicular Line:**
   - The slope of the line perpendicular to the given line is the negative reciprocal of the slope of the given line. If the slope of the given line is \( m \), then the slope of the perpendicular line will be \( -\frac{1}{m} \).

3. **Graph the Perpendicular Line:**
   - Use the calculated slope to graph the perpendicular line by starting at any point on the graph, and applying the slope to determine the direction and steepness of the line.

#### Example:
In the graph below, a line is provided. Follow the instructions to draw a line that is perpendicular to this given line.

**Graph Description:**
- The given image shows a Cartesian coordinate system with a grid.
- The blue line plotted on the graph passes through points (-1, -5) and (6, 8).
  
**Steps to Graph Perpendicular Line:**
- The slope \( m \) of the given blue line can be calculated as follows:
  \[ m = \frac{y_2 - y_1}{x_2 - x_1} = \frac{8 - (-5)}{6 - (-1)} = \frac{13}{7} \]

- The slope of the perpendicular line will be the negative reciprocal:
  \[ m_{\text{perpendicular}} = -\frac{1}{m} = -\frac{1}{\frac{13}{7}} = -\frac{7}{13} \]

- To draw the perpendicular line using the calculated slope, start from any convenient point on the graph and apply the slope \( -\frac{7}{13} \) to plot the line.

**Interactive Graph Feature:**
- Click and drag to plot a perpendicular line.
- The line will change colors when a parallel or perpendicular line is drawn accurately.

This interactive feature will help you visualize and confirm the accuracy of your perpendicular line graphing. 

Practice by plotting the perpendicular line on the graph provided using the steps outlined above.
