Active Calculus - Multivariable

Activity 9.6.2.
(a)
Write a scalar equation of the plane \(p_1\) passing through the point \((0, 2, 4)\) and perpendicular to the vector \(\vn=\langle 2, -1, 1\rangle\text{.}\)
(b)
Is the point \((2, 0, 2)\) on the plane \(p_1\text{?}\)
(c)
Write a scalar equation of the plane \(p_2\) that is parallel to \(p_1\) and passes through the point \((3, 0, 4)\text{.}\)
Hint.
Compare normal vectors of the planes.
(d)
Give parametric equations for the line \(\mathcal{L}\) passing through the point \((2,0,2)\) and perpendicular to the plane \(p_3\) described by the equation \(x+2y-2z = 7\text{.}\)
(e)
Find the point at which \(\mathcal{L}\) intersects \(p_3\text{.}\)
