Question
Use vectors to determine whether the points are collinear.$$(0,-2,-5),(3,4,4),(2,2,1)$$
Step 1
We can do this by subtracting the coordinates of the second point from the first point, and the third point from the second point. The vector between the first and second point is given by: \[\vec{AB} = (3-0, 4-(-2), 4-(-5)) = (3, 6, 9)\] The vector between the Show more…
