Question

Find the cartesian equation of the line which passes ·through the point (– 2, 4, – 5) and parallel to the line given by.

`(x + 3)/3 = (y - 4)/5 = (z + 8)/6`

विकल्प

• `z/6`

• `(z + 2)/6`

• `(z + 5)/6`

• `(z + 4)/6`

Answer 1

`(z + 5)/6`

Explanation:

The cartesian equation of the line passing through the point (– 2, 4, – 5) and parallel to the line,

`(x + 3)/3 = (y - 4)/5 = (z + 8)/6` is `(x + 2)/3 = (y - 4)/5 = (z + 5)/6`
