Lesson Explainer: Parallel and Perpendicular Vectors in Space

Given that the vectors A = (-4, 6) and B = (x, 12) are parallel vectors, determine the value of x. Solution. Since the vectors are parallel, we know that: B = c* A. Where c is some scalar value.

Parallel Vectors

Explanation: Two vectors A and B are parallel if and only if they are scalar multiples of one another. A = k B , k is a constant not equal to zero. Two vectors A and B
