Determine the Cartesian equation of the plane that a. contains the point P(-2, 6, 1) and has normal vector (2.-4,5) b. contains the point P(-2, 0, 6) and the line 42+2=51 Q3: (T=2) A line has 7 = (1, 2) + s(-2,3), sER, as its vector equation. On this line, the points A, B, C, and D correspond to parametric values s = 0, 1, 2, and 3, respectively. Show that each of the following is true: AC =2AB AD= 3AB
