1. Find the vector that passes through the points (-1, 2, 6) and (3,-7, 12). 2. Find two other nonzero vectors that are parallel to the vector in problem#1. 3. Are there real values for c, so that u=5i-9cj and v-7i-4cj are orthogonal? Justify. 1. Find the vector that passes through the points (-1, 2, 6) and (3,-7, 12). 2.
