8.4 Vector & Parametric Equations of a Plane (Grade 12 Calculus, MCV4U)

In the first example, point C should be C(4,1,1). I forgot a comma. In the last example, the parametric equation for y should read y = 1+ s - 3t and the z should read z = 1 + 4t. It's technically the same thing though since I used the AP vector as (0,3,-4) instead of (0,-3,4).
