A)

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?
(1 point)
–2
-1/2
1/2
2

To find the slope of a line, we can use the formula:

slope = (y2 - y1) / (x2 - x1)

Let's label the coordinates of the first airplane as (x1, y1) = (2, 1) and (x2, y2) = (4, 5).

slope = (5 - 1) / (4 - 2)
slope = 4 / 2
slope = 2

Therefore, the slope of a line that represents the path of another airplane that is traveling parallel to the first airplane is 2.
