# If P(1, 5, 4) and Q(4, 1, -2) be two given points, find the direction ratios of PQ.

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(x_{1}, y_{1}, z_{1}) and Q(x_{2}, y_{2}, z_{2}) be two given points then direction

ratios of PQ is given by x_{2} x_{1} , y_{2} y_{1} , z_{2} z_{1}

x_{1} = 1, y_{1} = 5 , z_{1} = 4 and x_{2} = 4, y_{2} = 1 , z_{2} = -2

Direction ratios of PQ is given by x_{2} x_{1} , y_{2} y_{1} , z_{2} z_{1}

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
