Here are a couple of short questions to look at before our next lesson.
- Verify that the points \(A(1,2,3)\), \(B(-2,0,0)\), and \(C(3,-2,-1)\) are not collinear.
- Find the vector equation of the plane that contains all three points from question 1.
- Find the Cartesian equation of the plane you determined in question 2.
- Verify your answers using GeoGebra.
