Segment XY represents the path of an airplane that passes through the coordinates (2, 1) and (4, 5). What is the slope of a line that represents the path of another airplane that is traveling parallel to the first airplane?

The slope of the path of the first airplane can be found using the formula (change in y)/(change in x):
slope = (5 - 1)/(4 - 2) = 4/2 = 2
Since the path of the second airplane is parallel to the first, it will have the same slope. Therefore, the slope of the line representing the path of the second airplane is 2.
