Answer 1

To determine whether the lines represented by the given tables intersect, we need to calculate the slopes of both lines.

1. **Identify the slope of each line:** The slope \( m \) for a linear graph can be calculated using the formula:

\[
m = \frac{y2 - y1}{x2 - x1}
\]

If we have two points from each table, we can calculate the slopes.

2. **Compare the slopes:**
- If the slopes are equal, the lines are parallel and do not intersect.
- If the slopes are different, the lines are not parallel and do intersect.
- If the slopes are negative reciprocals (i.e., their product is -1), then the lines are perpendicular. They will intersect at exactly one point.

3. **Conclusion:**
- If you know the points from both tables, plug them into the slope formula to compare their slopes.
- If the slopes are equal, then the answer is “No…these lines are parallel.”
- If the slopes are different, the answer is “Yes…these lines are not parallel nor perpendicular.”
- If the slopes are negative reciprocals, the answer is “Yes…these lines are perpendicular.”

Since you did not provide the actual data from the tables, I cannot calculate specific slope values, but this is how you would determine whether the lines intersect. If you provide the points, I can help with the calculations!
