If L is a line in 2spece or 3spece that passes through the points A and B, then the distance from a, point P to the line L is equal to the length of the component of the vector E that is orthogonal to the vector ?. P A B Use the method above to nd the distance from the point P (3, 1, 9) to the line through A(1,1,0) and B(2,3, 4). NOTE: Enter the exact
