Answer :

Given : P(1, 5, 4) and Q(4, 1, -2) be two given points


To find : direction ratios of PQ


Formula used : if P(x1, y1, z1) and Q(x2, y2, z2) be two given points then direction


ratios of PQ is given by x2 x1 , y2 y1 , z2 z1


x1 = 1, y1 = 5 , z1 = 4 and x2 = 4, y2 = 1 , z2 = -2


Direction ratios of PQ is given by x2 x1 , y2 y1 , z2 z1


Direction ratios of PQ is given by 4 1, 1 5, 2 4


Direction ratios of PQ is given by 3, 4, 6


Direction ratios of PQ is given by 3, 4, 6
