The correct option (B) 4x + 14y – 11z = 36
Explanation:
Lines: (x/2) = [(y –1)/1] = [(z + 2)/2] and
[(2x + 3)/4] = [(3 – y)/(– 1)] = (z/2)
i.e. [{x + (3/2)}/2] = [(y – 3)/1] = (z/2)
∴ vector a = (0, 1, – 2) and vector ℓ = (2, 1, 2)
also vector b = [{(– 3)/2}, 3, 0] and vector m = (2, 1, 2)
vector ℓ = vector m ⇒ lines are parallel.
