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?

To determine the slope of the line passing through the points (2, 1) and (4, 5), we can use the slope formula:
slope (m) = (y2 - y1) / (x2 - x1)
Plugging in the values from the points given:
m = (5 - 1) / (4 - 2) = 4 / 2 = 2
So, the slope of the line representing the path of the first airplane is 2.
A line that is parallel to another line will have the same slope, so the slope of a line that represents the path of another airplane that is traveling parallel to the first airplane will also be 2.
