1. find an equation of the plane. the plane through the points (0, 8, 8), (8, 0, 8), and (8, 8, 0)2. find parametric equations and symmetric equations for the line. (use the parameter t.) the line through(3, ? 1, 5) and parallel to the line x + 4 = y/2 = z-53. find the point at which the line intersects the given plane. x = 4 ? t, y = 2 + t, z = 5t; x ? y + 4z = 204. determine whether the planes are parallel, perpendicular, or neither. 2x + 8y ? 6z = 1, ? 15x + 30y + 35z = 0if neither, find the angle between them. (if the planes are parallel or perpendicular, enter parallel or perpendicular, respectively.)
