Final answer:
The slope of the line that passes through the points (-9, 5) and (-17, 5) is 0, indicating a horizontal line.
Step-by-step explanation:
The slope of a line that passes through two points can be calculated using the formula (y2 - y1) / (x2 - x1), where (x1, y1) and (x2, y2) are the coordinates of the two points. For the points (-9, 5) and (-17, 5), the slope can be determined as follows:
- y2 - y1 = 5 - 5 = 0
- x2 - x1 = -17 - (-9) = -17 + 9 = -8
Therefore, the slope is 0 / -8, which simplifies to 0. Since the slope is 0, this indicates that the line is horizontal and there is no rise between the two points.
