Final answer:
A line with a slope of -1 is a straight line with a negative slope. The ordered pairs (-8, 8) and (2, 2) could be points on a parallel line.
Step-by-step explanation:
A line with a slope of -1 is a straight line with a negative slope. This means that for every increase of 1 unit in the horizontal direction, there is a decrease of 1 unit in the vertical direction.
To find points on a parallel line, we need to look for lines that have the same slope, which in this case is -1. So, the ordered pairs (-8, 8) and (2, 2) could be points on a parallel line.
