QUESTION #16 Image of a Point and Distance
Let Q(a, b, c) be the image of the point P(3, 2, 1) in the line (x - 1)/(1) = (y)/(2) = (z - 1)/(1). Then the distance of Q from the line (x - 9)/(3) = (y - 9)/(2) = (z - 5)/(-2) is

QUESTION #24 Distance Along a Vector
If the distance of the point P(43, α, β), β < 0, from the line r = 4 i - k + μ(2 i + 3 k), μ in R along a line with direction ratios 3, -1, 0 is 13√(10), then α² + β² is equal to
