Question

The line x = 1 + 5μ, y = −5 + μ, z = −6 − 3μ passes through which of the following point?

Options

• (1, −5, 6)

• (1, 5, 6)

• (1, −5, −6)

• (−1, −5, 6)

Answer 1

(1, −5, −6)

Explanation:

Given: x = 1 + 5μ, y = −5 + μ, z = −6 − 3μ

⇒ Equation of a line 

`(x - 1)/5 = (y + 5)/1 = (z + 6)/-3 = μ`

Passes points (1, −5, −6)
