Question 44

MediumOriginal question

What is the Cartesian equation of the line through (1,−2,3)(1, -2, 3) parallel to the line x−42=y+1−3=z−26\frac{x - 4}{2} = \frac{y + 1}{-3} = \frac{z - 2}{6}?

CorrectNot quiteAnswer C

Correct answer: C

Explanation

  1. A parallel line has the same direction ratios, 2,−3,62, -3, 6.

  2. Through (1,−2,3)(1, -2, 3): x−12=y+2−3=z−36\frac{x - 1}{2} = \frac{y + 2}{-3} = \frac{z - 3}{6}.

Worth noting

Taking 4,−1,24, -1, 2 as the direction uses the given line's point, not its direction.
