2 Let I be the line in R³ that consists of all scalar multiples of the vector w = -[] 2 Find the reflection of the vector v = reflection = [8] 8 in the line L.

Compute the orthogonal projection of i = -5 onto the line L through 2 and the origin.

Determine the vector equation for the line that is parallel to 7 = [1,5,-7]+t[2,-1,5] with the same x-intercept as [x, y, z]=[-1,8,6]+t[-2,4,3]. 3.
