Segment XY represents the path of an airplane that passes through the coordinates (3, 5)
and (12, −1)

The slope of a line can be found using the formula:
slope = (change in y-coordinates) / (change in x-coordinates)
For the first airplane, the change in y-coordinates is -1 - 5 = -6 and the change in x-coordinates is 12 - 3 = 9.
So, the slope of the first airplane's path is:
slope = (-6) / (9) = -2/3
Since the second airplane is traveling parallel to the first airplane, it will have the same slope. Therefore, the slope of the line representing the path of another airplane is -2/3.
