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?

Explanation:
Calculate the slope of XY using the
color(blue)"gradient formula"gradient formula
color(orange)"Reminder " color(red)(bar(ul(|color(white)(2/2)color(black)(m=(y_2-y_1)/(x_2-x_1))color(white)(2/2)|)))
where m represents the slope and(x_1,y_1),(x_2,y_2)" 2 coordinate points." The 2 points here are (2 ,1) and (4 ,5)
let
(x_1,y_1)=(2,1)" and " (x_2,y_2)=(4,5)
rArrm=(5-1)/(4-2)=4/2=2 The following fact must be known to complete the question.
color(blue)"parallel lines have equal slopes" Thus the slope of line of parallel airplane is also 2
