Slopes of perpendicular segments are always negative reciprocal of each other. Or, we can say product of slopes of perpendicular segments is always -1.
Given the slope of PQ is 5/2.
So the slope of its perpendicular segment should be -2/5.
Finding slopes of given options:-

slope \: of \: xy = ( - 10 - ( - 5))/(4 - 2) = ( - 5)/(2)

slope \: of \: tu = (7 - 2)/(2 - 0) = (5)/(2)

slope \: of \: rs = ( - 6 - ( - 4))/(8 - 3) = ( - 2)/(5)

slope \: of \: vw = (9 - 5)/(4 - 14) = (4)/( - 10) = ( - 2)/(5)
From above calculations, it is clearly visible that slopes of RS and VW are negative reciprocal of slope of PQ.

So, correct answers are RS and VW.
