The question in the images appears to be asking you to analyze pairs of lines and determine whether they are parallel, perpendicular, or neither based on the provided graph and coordinates.

Here’s a step-by-step breakdown of what to do:

1. Identifying Parallel Lines: Two lines are parallel if they have the same slope. This means that their directions are identical, and they never meet, no matter how far they are extended.

2. Identifying Perpendicular Lines: Two lines are perpendicular if the product of their slopes is -1. This means that the lines meet at a 90-degree angle.

3. Neither: If two lines are neither parallel nor perpendicular, then they must intersect at some other angle (not 90 degrees), and their slopes are neither identical nor negative reciprocals of each other.

Step-by-step for the pairs:

• Lines AB and CD: Check if the slopes are equal (for parallel) or if the product of their slopes is -1 (for perpendicular).
• Lines JK and AB: Same process.
• Lines JK and GH: Same process.
• Lines EF and GH: Same process.
• Lines JK and EF: Same process.

It looks like you are asked to determine the relationship (parallel, perpendicular, or neither) for each of these pairs.

Would you like to analyze these step-by-step using the coordinates or slopes provided in the image? I can guide you through each pair.

Here are 5 questions to help expand your understanding:

1. How do you calculate the slope of a line using two points?
2. What is the relationship between slopes of perpendicular lines?
3. Can two lines with negative slopes still be parallel?
4. What is the formula to determine if two lines are neither parallel nor perpendicular?
5. How does the orientation of a line affect whether it is parallel or perpendicular to another line?

Tip: Always remember that slopes can be calculated as $\frac{y_2 - y_1}{x_2 - x_1}$, which helps in identifying parallel or perpendicular lines quickly.
