Consider the four points below: (2,4,-2), (-7, 16,4), (5,0,-4), and (-4,-12,8). Part a. [10 points] Three of these points are colinear, find a scalar parametric representation for this line and identify the point not on this line. Part b. [5 points] Find the plane which contains all four points. Consider the four points below: (2,4,-2), (-7, 16,4), (5,0,-4), and (-4,-12,8). Part a.
