If P(1, 5, 4) and

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
