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?

parallel lines have the same slope. So we will find the slope by using the slope formula.
slope = (y2 - y1) / (x2 - x1)
(2,1)...x1 = 2 and y1 = 1
(4,5)...x2 = 4 and y2 = 5
now we sub
slope = (5 - 1) / (4 - 2)
slope = 4/2 -- reduce
slope = 2
