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,
