?Let P be a point not on the line L that passes through the points Q and R. (a) Show
Chapter 12, Problem 45(choose chapter or problem)
Let P be a point not on the line L that passes through the points Q and R.
(a) Show that the distance d from the point P to the line L is
\(d=\frac{|a \times b|}{|a|}\)
Where \(a=\overrightarrow{Q R}\) and \(b=\overrightarrow{Q P}\).
(b) Use the formula in part (a) to find the distance from the point \(P(1, 1, 1)\) to the line through \(Q(0, 6, 8)\) and \(R(ー1, 4, 7)\).
